Exact Calendar and Day Difference
Use the calendar breakdown for ages, contracts and anniversaries, or the exact day total for schedules and deadlines. UTC date arithmetic keeps the count stable across daylight-saving changes.
Frequently asked questions
How are days between dates calculated?
The exact total uses UTC calendar dates so daylight-saving changes do not add or remove a day.
Can I include the end date?
Yes. Enable Include end date to count both the starting and ending calendar day.
Does it show months and years?
Yes. It shows a calendar breakdown plus exact total days and weeks.
Are my dates saved?
No. The calculation runs locally and nothing is stored.
