Date Difference
Total days and exact Y/M/D between two dates.
Find the gap between any two dates
Enter a start and end date to calculate the exact span between them. The tool returns both the total number of days and a precise years/months/days breakdown - ideal for age-on-date checks, project plans, visa applications, or events.
Best practices
- Choose dates in the same timezone you care about. We assume local midnight for each selection.
- Set the end date to today if you want to include the current day in the result.
- Ensure the end date is on or after the start date to avoid negative spans.
What the result shows
We first count whole calendar years, then remaining months, then days. Leap years, short months, and year boundaries are baked in so you can trust the output when filling official forms.
Example timelines
- Start → End
- 1 Jan 2024 → 31 Mar 2024 = 90 days (0y 2m 30d)
- Start → End
- 15 May 2023 → 10 Feb 2025 = 637 days (1y 8m 26d)
Common scenarios
- Track probation periods, maternity leave windows, and project deadlines.
- Calculate age on a specific date for insurance, sports, or admissions.
- Compare visa or permit validity periods with renewal dates.

FAQ
Does this handle timezone differences? We treat dates as local calendar days. For multi-timezone schedules, align on a single timezone first.
Can I include hours and minutes? Not yet—this tool is date-only. A detailed time difference calculator is on the roadmap.
