How it works
Calculate the exact date a selected number of days ago.
We normalize civil dates to avoid timezone and daylight-saving errors.
What happens when days are subtracted
The tool moves backward by the selected number of consecutive calendar days and handles month, year and leap-day boundaries.
It returns the exact earlier date and its weekday so past periods can be checked quickly.
Tips for a useful result
- Enter a whole number equal to or greater than zero.
- Weekends are included because this operation uses calendar days.
- Use the days-between tool to verify a reconstructed period.
