When is this useful?
- Deadlines and timeframes. Signed a contract on March 3rd for 90 days and want to immediately know the exact end date? Or vice versa: you know the final deadline and need to understand how many days are left to complete it.
- For lawyers and accountants. Statute of limitations, filing deadlines, payment schedules — all of these are tied to a specific number of working days. You could calculate them manually using a calendar, but why bother?
- Dates in the future and past. Warranty is valid for 2 years from purchase? Trial period is 14 days? The project is planned for 6 months? Simply enter the starting date, add the interval, and see the result instantly.
- Time elapsed. How many days since the beginning of the year, from the project launch, or since the last update — any interval from a specific date until today.
⚠️ Working days are calculated excluding Saturdays and Sundays. Public holidays are not included — check your country's official holiday calendar.
