Pick a start and end date to get the exact day count, week count, year/month/day breakdown, and business day count.
The calculator takes the exact calendar difference between the two dates, inclusive of leap years, and shows it as a raw day count, in weeks, and broken down into years/months/days.
Monday through Friday, counted between the two dates. It doesn't exclude public holidays, since those vary by country and calendar — treat it as a Mon–Fri count, not an official working-day count for payroll or legal deadlines.
No — enter them in either order. The result is always shown as a positive count, and works the same whether you're counting forward to a future date or back to a past one.
The day count itself is exact, but many contracts define 'business days' or 'working days' with specific rules (excluding public holidays, or counting from the day after signing) that vary by jurisdiction and agreement — always check the exact wording of a contract rather than relying solely on a general-purpose calculator for legal deadlines.
Business days here count Monday–Friday only, excluding weekends — it doesn't subtract public holidays, since those differ by country and calendar, so the true number of working days may be a few less than shown if holidays fall in that range.
Worked example: from 1 January 2026 to 31 December 2026 is 364 days — one short of a full year because the count runs from Jan 1 to Dec 31 inclusive-exclusive, illustrating why 'a year' and '365 days between two dates' don't always align exactly depending on which dates you pick.
