Date Difference
Find the number of calendar days between two dates, with a clear choice about whether to include both dates.
Choose two dates to see the difference.
Counts calendar days, including weekends and holidays. Daylight-saving changes do not affect the result.
How to use Date Difference
Choose a start and end date. By default, the same date gives zero elapsed days. Include the end date to count both dates; the same date then counts as one day.
Do time zones or daylight-saving changes affect the answer?
No. This compares calendar dates, not local clock hours. Weekends and holidays count as ordinary days. Swap dates if your end date is earlier than the start.
