Calculate Calendar Days
Calculate the number of calendar days between two dates. Including working days, weeks, and remaining days.
Calculate calendar days between two dates
With this calendar day calculator, you can easily calculate the number of days between two dates. This is useful for:
- Calculate contract duration
- Determine gestational age
- Holiday planning
- Project duration
- Statutory time limits
- Subscriptions or trial periods
Including or excluding start date?
Sometimes the start date counts (for example, for statutory deadlines), sometimes it does not (for schedules). Therefore, you can check this yourself.
Calculate working days
Do you only want to count working days (Monday to Friday)?
Then enable the “Working days only” option.
Please note: official holidays are not automatically excluded.
How is the difference calculated?
The tool calculates the exact difference in milliseconds between both dates and converts this to calendar days. The result is then also displayed in weeks + remaining days for additional insight.
