Count the days

Pick two dates and the day counter shows how many days are between them, plus the same span in weeks, months and years. From 1 January to 25 December 2026 is 358 days. Use it to count days since an event, days until a deadline or holiday, or to check how long a contract or subscription runs. Leap years are counted correctly.
