Recruitment marketing·Hiring data
The question an employer is actually asking is not when hiring season is — it is how far ahead of it to start advertising. Below is the monthly hiring curve for ten industries, built from federal hiring counts rather than from opinion: which month your competitors do most of their hiring, which month they do least, and how far apart those two are in your sector.
The short version: across all industries, June is the busiest month for hires and December the quietest, about 59% apart. But the national curve is close to useless on its own — the industries underneath it peak in five different months and one of them runs the calendar backwards. In every case the month to advertise is two to three months before the month you need people working, because that is when you are bidding against the fewest other employers.
Peak hiring months by industry
Each row below is one industry’s own year. 100 is an average month for that industry, so the numbers say when that sector hires, not how big it is. The gold cell is the peak month; the grey cell is the low.
| Industry | Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec | Peak | Low |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| All industries | 97 | 85 | 93 | 107 | 112 | 116 | 111 | 110 | 100 | 105 | 89 | 73 | Jun | Dec |
| Construction | 100 | 87 | 114 | 121 | 122 | 118 | 116 | 104 | 93 | 96 | 73 | 54 | May | Dec |
| Manufacturing | 106 | 93 | 97 | 104 | 109 | 122 | 114 | 109 | 103 | 102 | 78 | 64 | Jun | Dec |
| Retail trade | 85 | 86 | 93 | 100 | 110 | 117 | 103 | 108 | 97 | 115 | 110 | 76 | Jun | Dec |
| Transportation, warehousing and utilities | 85 | 70 | 66 | 78 | 89 | 93 | 92 | 95 | 102 | 148 | 178 | 103 | Nov | Mar |
| Health care and social assistance | 104 | 87 | 88 | 106 | 103 | 108 | 117 | 108 | 105 | 110 | 85 | 80 | Jul | Dec |
| Accommodation and food services | 89 | 82 | 96 | 116 | 120 | 122 | 110 | 112 | 101 | 98 | 80 | 74 | Jun | Dec |
| Professional and business services | 103 | 94 | 103 | 114 | 108 | 109 | 110 | 99 | 96 | 106 | 84 | 74 | Apr | Dec |
| Leisure and hospitality | 86 | 80 | 97 | 122 | 131 | 128 | 107 | 108 | 97 | 94 | 78 | 72 | May | Dec |
| Educational services | 121 | 72 | 66 | 72 | 88 | 132 | 123 | 175 | 129 | 107 | 69 | 45 | Aug | Dec |
Read down the December column. Every industry except transportation and warehousing has its worst hiring month in December, and most of them are 20 to 55% below their own average. Read across the top rows and the peaks are scattered from April to November. That scatter is the whole point: "hiring season" is a sector-level fact, not a national one.
The four shapes in the data
The spring build, and it has moved. Construction, leisure and hospitality, and accommodation and food services all peak between April and June and collapse in November and December. Construction is the sharpest of the three, running 122 in May against 54 in December — a 2.26x swing. One detail worth having if you hire trades: in the 2015 to 2019 average, construction’s peak month was April at an index of 139. In the 2021 to 2025 average it is May at 122. The season has shifted about a month later and flattened noticeably, which means the old advice to have crews hired by April is now early.
The summer peak. Manufacturing, retail and the national aggregate all top out in June. For manufacturing that is 122 against a December low of 64. This is the curve most people have in mind when they say "hiring season", and it is why a June posting competes with more employers than a posting in any other month.
The industry that runs backwards. Transportation, warehousing and utilities peaks in November at 178 — 78% above its own average and the single largest monthly spike in the dataset — with October at 148 and a trough in March at 66. Peak-season parcel, freight and fulfillment hiring inverts the national calendar completely. If you are a carrier or a 3PL, the months when everyone else is fighting over candidates are your quiet months, and the months when the general market has gone home are your crunch.
The flat industries. Health care and social assistance is the least seasonal sector in the data: a peak of 117 in July against a low of 80 in December, a 1.46x swing, and eight months of the year sitting between 100 and 110. Professional and business services and retail are similarly flat. For a senior living operator or a home care agency, there is no month worth waiting for — which is genuinely useful, because it means a hiring problem in March is a process problem, not a seasonal one.
Education is the outlier at both ends: an index of 175 in August and 45 in December, a 3.89x swing, the most seasonal sector in the economy and the only one where being a month late means missing the year.
Hires are not applicants, and the difference decides what you do
There is a trap in this data that most articles walk straight into. JOLTS counts hires — people who started a job. A busy hiring month therefore means two things at once: more people are moving, and more employers are competing for them. It does not mean candidates are easier to reach.
For an employer buying attention, the second effect is the one that shows up on the invoice. Social job advertising is an auction: you are bidding against every other employer trying to reach the same people in the same feed. In June, in a sector that peaks in June, you are bidding into the densest month of the year.
That does not mean you should hire in December. It means the useful question is not "when is hiring season" but "when do I need people working, and how far ahead of the crowd can I start". A construction company that starts recruiting in February for a May crew is buying the same candidates in a quieter auction. A carrier staffing for peak is doing the reverse and should be hiring in August.
The parts of the cost you control matter more than the month. Across 891 campaigns in our 2026 benchmark data, campaigns converting under 10% of clicks into applicants paid $53.77 per applicant, and campaigns converting over 20% paid $4.41 — a twelve-fold difference driven entirely by the posting and the application form. Frequency does the same thing: once the same person has seen an ad more than three times in a month the median cost per applicant roughly doubles, from $7.85 under 1.5 impressions each to $26.78 over 4.0. No month of the year moves a number that far.
Your hiring season
When to start recruiting, by what you are hiring
Take the month you need people working, then work backwards. Frontline roles in our data take a median of about four weeks from campaign launch to a filled shift once the posting is right; roles with a license or a background check take longer.
| If you are hiring | Your sector peaks in | Start advertising | Why |
|---|---|---|---|
| Construction and trades crews | May | February–March | The spring peak has moved a month later and flattened; February is still quiet and the candidates are still working out their season. |
| Warehouse, parcel and freight for peak | November | August | November runs 78% above the sector average. Everything you have not hired by late September you will be paying a premium for. |
| Manufacturing and production | June | March–April | The June peak is the most crowded auction of the year for this sector. |
| Restaurants, hotels and seasonal hospitality | May–June | March | Leisure and hospitality runs 131 in May against 72 in December — the steepest spring in the service economy. |
| Healthcare, senior living and home care | July, barely | Whenever the req opens | A 1.46x swing is not a season. If you cannot fill in March, the posting is the problem. |
| Schools and education support | August | April–May | An index of 175 in August and 45 in December. Miss it and you wait a year. |
| Retail for the holidays | June, then October | August | Retail has two bumps: a June peak at 117 and a second at 115 in October and 110 in November. |
Best day and time to post a job
Boostpoint does not publish a best day or time to post a job, because our benchmark does not break campaigns out by posting day or hour; what it does show is that across 891 campaigns the apply rate after the click explained 70% of the variation in cost per applicant, with a median campaign cost of $13.88 per applicant. We are not going to estimate day-of-week figures we do not have. Here is what the published data does support, and how to time the parts you control.
What the data supports
- The month matters. The curves above show each sector's peak hiring month. Start advertising two to three months ahead of it, when fewer employers are bidding for the same people.
- The application matters more. Campaigns converting under 5% of clicks paid a median $53.77 per applicant; campaigns converting 20 to 35% paid $4.41.
- Freshness matters after launch. Once the same person has seen an ad more than three times in a month, median cost per applicant rises to $18.76, and above four times to $26.78, against $7.85 under 1.5. On social, the “when” that counts is refreshing creative before that point, not the hour you pressed publish.
How to time the parts you control
Social job ads are delivered continuously to people as they scroll, so there is no single moment of posting to optimize the way there is on a job board that sorts by date. The timing that matters is on your side of the funnel:
- Launch when someone can answer. Start a campaign on a day when the person following up is working the next several days, not before a long weekend or a vacation.
- Reply fast, whatever the hour. An automated text on submission, then a call the same day. Applicants who apply at 10 p.m. can still get a reply by 10:01.
- Offer interview slots that fit the shift. Night-shift candidates are awake at different hours from day-shift candidates.
- Check frequency weekly. Act when a campaign passes 2.5 in a month: widen the audience or rotate the creative.
If you post on job boards as well, test the day yourself: run the same posting on different launch days over a few cycles and compare applicants in the first week. Your own funnel is the only reliable dataset for this question. The full cost figures are on our 2026 benchmark page. Cost per applicant is not cost per hire.
What about the January myth?
The most repeated claim about hiring season is that January and February are the big hiring months because budgets reset. The data does not support it as a general rule: January comes in at 97 and February at 85 across all industries, both below an average month, and February is the second-worst month of the year nationally.
There are two real exceptions. Education runs 121 in January — the mid-year staffing correction is genuine. And manufacturing sits slightly above average at 106. Everywhere else, the January hiring surge is an artefact of counting job postings rather than hires: postings do spike when budgets open, but the people do not start until spring.
How this was built, and what it cannot tell you
Source: BLS Job Openings and Labor Turnover Survey, hires level, not seasonally adjusted, by industry, monthly, averaged across 2021 to 2025 and indexed to each industry’s own twelve-month mean. 2020 is excluded because pandemic shutdowns and the rehiring spike would distort every curve. The 2015 to 2019 comparison quoted for construction uses the same method on the five pre-pandemic years.
Three limits worth stating. This is national data, and a regional construction season in Phoenix is not the one in Minneapolis. It is industry-level, so a specific role can run against its sector — nurse graduate hiring peaks in May and June regardless of what the health care line does. And it counts hires rather than applications, so it tells you when the market is busy, not when your own funnel converts best. For that, the only reliable dataset is your own.
Frequently asked questions
When is hiring season?
Across all US industries, June is the busiest hiring month and December the quietest — June runs about 59% ahead of December in federal hiring counts. But the national curve hides five different sector calendars: construction peaks in May, transportation and warehousing in November, education in August, and health care barely peaks at all.
What are the peak hiring months?
Nationally, May through August, with June the highest. April and October are moderately above average. November, December, February and March are the four below-average months, with December the lowest by a wide margin in every industry except transportation and warehousing.
When do companies hire the most?
June, measured by people actually starting jobs. In the 2021 to 2025 average, June sits at an index of 116 against an average month of 100 and December at 73. Because everyone else is hiring then too, June is also the most competitive month to advertise a job in.
When is the best month to hire?
The best month to advertise is usually two to three months before your sector peaks, not during the peak. A construction employer who needs crews in May should be advertising in February; a warehouse staffing for peak season in November should be advertising in August. You reach the same people in a less crowded auction.
What is the worst month for hiring?
December in almost every industry — 45 for education, 54 for construction, 64 for manufacturing, 73 across all industries. February is the second worst nationally at 85. The exception is transportation and warehousing, whose worst month is March.
Does hiring really slow down in December?
Yes, and by more than most people expect. December is the lowest hiring month of the year in nine of the ten industry groups measured, typically 20 to 55% below that industry’s own average. Transportation and warehousing is the exception, still running slightly above average at 103 as peak-season hiring continues.
When do companies start hiring for seasonal work?
It depends which season. Retail and warehouse peak-season hiring builds through October and November, with the transportation and warehousing index hitting 178 in November. Spring and summer seasonal work in construction, landscaping and hospitality is hired from March through June. Schools hire in August.
Is January a big hiring month?
Not generally. January sits at 97 against an average month of 100, and February at 85. The belief that January is a hiring surge comes from job postings rather than hires: budgets open and reqs are posted in January, but most of those people do not start until spring. Education is the real exception, at 121 in January.
Does hiring season mean more candidates are available?
It means more people are moving, and also that more employers are competing for them. JOLTS counts hires, not applications. For an employer buying advertising, a busy month is a more expensive auction, which is why starting ahead of your sector’s peak generally beats recruiting into it.
When do jobs hire the most?
June, by a wide margin, with May close behind. On the not-seasonally-adjusted federal hires series, June runs about 59% ahead of December. The implication most employers miss is that June is therefore also the month in which your posting competes with the largest number of other employers, so the busiest month for hiring is not automatically the best month to be advertising in.
When does hiring season start?
There is no single national hiring season, which is why the question is usually answered badly. Across all industries hires rise through the spring to a June peak, but the sector curves above are what matter: leisure and hospitality peaks in May, education in August, transportation and warehousing in November, and health care barely moves at all. The useful question is not when the season starts but how far ahead of your own peak to begin advertising — which in the table above is generally two to three months.
When do jobs start hiring for seasonal work?
Earlier than the season itself, and earlier than most candidates expect. Earlier than the work, and earlier than most candidates expect. On the curves above, retail and warehouse hiring for the holiday peak should be advertising from August for work starting in October and November, and spring and summer hospitality should be advertising from March. If you are advertising in the month the work begins, you are bidding against every employer who started three months earlier.
What is the best day to post a job?
Boostpoint does not publish day-of-week data, so we cannot name a best day. What the 2026 benchmark does show is that the apply rate after the click explained 70% of the variation in cost per applicant across 891 campaigns, and our hiring curves show that starting two to three months before your sector's peak month is the timing decision with data behind it.
What time of day should I post a job ad?
On social media, job ads are delivered continuously as people scroll, so the posting time matters less than your response time. Launch when someone can follow up for the next several days, text applicants automatically on submission, and call the same day. Boostpoint does not publish time-of-day data; test launch timing against your own applicant counts if you post on job boards.

Your hiring month matters less than your apply rate
Across 891 campaigns, the gap between a good posting and a bad one is twelve times the cost per applicant. No month of the year is worth that much.
