Every year, 365 calendar days look like a lot of time on paper. Once you strip out weekends, public holidays, and the vacation you actually take, the number of real, billable, productive days you have left is far smaller than most people assume. This working days calculator does that subtraction for you in seconds: start with the total calendar days in your period, remove weekends, holidays, and PTO, and you are left with the honest count of business days available.
Freelancers use it to price contracts, managers use it to forecast capacity, and employees use it to understand how much of the year they actually spend on the job. The math is simple, but the answer drives real decisions — from how many client projects you can take on to whether your salary break-down per day makes sense.
How to Use
- Enter the Total Calendar Days in your period. A full non-leap year is 365; a leap year is 366. If you are measuring a quarter or a specific project window, type the exact number of days between your start and end date.
- Set Weekend Days to Remove. For a standard Monday–Friday schedule this is almost always 104 (52 Saturdays plus 52 Sundays). If you work a rotating shift or a six-day week, adjust the number to match.
- Add Paid Holidays. The US federal calendar has 11 public holidays. Your company may close for more days — for example, between Christmas and New Year — or observe fewer. Type whatever your official holiday calendar shows.
- Enter PTO / Vacation Days if you want to see your available working days rather than the gross business days. This is where sick leave, personal days, and planned vacation go.
- Read the result card. The headline number is your Working Days Available, and below it the same days are converted into work weeks, work months, and an 8-hour billable-hour total.
The engine works by subtraction: workingDays = periodDays − weekendDays − holidays − PTO. It does not double-count days that fall outside your period, so if you are measuring a short project window, only enter the weekends and holidays that actually occur inside that window.
The Standard Year: 250 Working Days
For a typical US full-time employee, the math looks like this:
- 365 calendar days in a non-leap year
- −104 weekend days (52 Saturdays + 52 Sundays)
- −11 federal holidays
- = 250 working days per year
That is the baseline almost every salary, contract, and freelance rate is built on. Spread across an average of 21.67 working days per month, the year breaks into roughly 50 working weeks, or about 2,080 working hours at an 8-hour day. Once you add 15 days of PTO, the number drops to 235 working days and 1,880 hours — which is why salaried pay and freelance day rates are normally quoted against the 250-day baseline, not the 365-day calendar.
If you earn a $75,000 salary, your effective pay per working day is about $300 ($75,000 ÷ 250), and per working hour roughly $36. Freelancers billing $600 per day are implicitly pricing themselves at two traditional US salary days of output. Run your own numbers through the calculator before quoting a rate or signing a contract.
Why This Number Matters
Most business planning errors come from treating the year as 365 usable days. It is not. A few concrete consequences:
- Capacity planning. A team of 5 engineers has 1,250 working days per year before PTO. With 15 PTO days each, that falls to 1,175. Plan sprints against 1,175, not 1,250.
- Freelance pricing. If you want to earn $120,000 a year and plan 20 billable days a month (240 per year), your minimum day rate is $500. Anything below that and you are effectively underpaying yourself.
- Salary negotiation. Asking for a raise of $10,000 on a $90,000 base is a $40-per-working-day increase. Framing it that way makes the number easier to justify.
- Project deadlines. A 100-task project at 2 tasks per engineer per working day needs 50 working days — about 10 weeks, or 2.5 calendar months once weekends and holidays are added back.
Examples
Example 1 — Standard US employee. Total days = 365, weekends = 104, holidays = 11, PTO = 15. The result is 235 working days, about 47 work-weeks, 10.8 work-months, and 1,880 billable hours. On a $80,000 salary that works out to roughly $340 per day and $42 per hour.
Example 2 — Freelancer pricing. A contractor wants to net $6,000 per month after expenses. With 21.67 working days per month, the minimum day rate is $277. Adding 20 days of unpaid vacation across the year drops the annual working days to about 230 and pushes the required day rate to roughly $313 to hit the same yearly target.
Example 3 — Q4 project window. A project runs from October 1 to December 31 — 92 calendar days. That window contains 26 weekend days, 3 federal holidays (Columbus Day, Veterans Day, Thanksgiving), and the team plans 5 PTO days each. Result: 92 − 26 − 3 − 5 = 58 working days, or about 11.6 work-weeks. Planning around 58 days, not 92, prevents an over-promised deadline.
FAQ
How many working days are there in a year?
In a standard non-leap year with a Monday–Friday schedule, the math is 365 calendar days minus 104 weekend days minus 11 federal holidays, which gives 250 working days. With 15 days of PTO, the available working days drop to 235.
How many workweeks are in a year?
There are 52 calendar weeks in a year. After removing weekends and holidays, the typical employee works about 50 full weeks (250 days ÷ 5 days per week). With two additional weeks of PTO, that drops to 48 weeks.
How do I count business days between two dates?
Count the total calendar days between your start and end date inclusive, subtract the number of Saturdays and Sundays in that window, subtract any public holidays that fall on weekdays, and subtract any planned PTO. The calculator on this page automates that subtraction once you type in the four numbers.
Does the calculator include federal holidays?
Yes, the default value is 11 — the number of US federal holidays (New Year's Day, MLK Jr. Day, Presidents Day, Memorial Day, Juneteenth, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving, Christmas). If your company observes more or fewer holidays, simply adjust the Paid Holidays field.
How many working hours are in a year?
At the standard 8-hour workday, 250 working days equals 2,000 working hours per year. After 15 PTO days (120 hours), that falls to 1,880 hours. This is the number salary and freelance rates are normally benchmarked against.
Should I count half-days or company half-holidays?
Yes — if your company closes early before a holiday, type a fractional day into the PTO or holidays field. For example, a half-day on Christmas Eve adds up as 0.5 day removed. The calculator accepts decimals.
