How many days until, without weekends
A plain day count between two dates includes weekends, which isn't what you usually want for work deadlines, shipping estimates, or notice periods. This calculator only counts Monday through Friday — and lets you exclude specific holiday dates on top of that, so the number you get back is the number of actual working days, not just calendar days. If you also need to calculate the hours between two times, use the Hours Calculator.
How many working days between two dates
Enter a start and end date and the calculator counts the business days between them. Whether the start and end dates themselves count depends on what you're asking — "5 business days starting today" and "5 business days from tomorrow" are genuinely different counts, so both the start date and end date have their own include/exclude option, defaulting to included. The breakdown below the result shows exactly how the total splits into business days, weekend days, and any holidays you've excluded. If you want to count the total elapsed days without excluding weekends, see the Days Between Dates calculator.
How many days left in the year
Select "Days left in [year]" to set the range from today through December 31 automatically, then add US Federal Holidays or your own dates if you want those excluded from the count too.
Frequently asked questions
Does this only work for US holidays?
No. The holiday list is fully editable — add any date from any country, or your company's specific closures. "Add US Federal Holidays" is just a shortcut that fills in the 11 current US federal holidays automatically; you don't need to use it if it doesn't apply to you.
What happens if a US federal holiday falls on a weekend?
The calculator uses each holiday's officially observed date, following the federal rule: a holiday that falls on a Saturday is observed the preceding Friday, and one that falls on a Sunday is observed the following Monday.
