weeks (and days)
Precisely count calendar and business days, weeks, months and years between two dates. Add and subtract periods. Everything runs in your browser — no data leaves it.
The calculator quickly counts how many days have passed or remain between two dates and lets you add or subtract a period from a date. It is handy for vacations, contract terms, deadlines, age and days until an event.
Pick a start and end date — the result in days, weeks, months and years appears instantly. The «Include the last day» checkbox adds the end date to the count.
Business days are all days except Saturday and Sunday. Public holidays and shifts are not counted.
No, all calculations happen in your browser.
