How to Calculate the Number of Days Between Two Dates
Enter a start date and an end date above to instantly calculate the days between dates, along with the total weeks, hours and minutes, and a full years/months/days breakdown.
Inclusive vs Exclusive Counting
This calculator returns the straightforward gap between two dates (exclusive counting). Some contracts and notice periods use inclusive counting instead — counting both the start and end date — which adds one extra day to this result.
Common Uses
Rental and lease terms, project deadlines, visa day-limit tracking, pregnancy and medical day counts, and 'days since' streak tracking are among the most common reasons people calculate months between dates or years between dates.
Frequently Asked Questions
Q: How many days are there between two dates?
A: Enter a start date and an end date into the calculator above; it instantly returns the exact number of days, weeks, hours and minutes between them.
Q: Does this calculate months and years between dates too?
A: Yes — alongside the total day count, the calculator shows a full years/months/days breakdown of the gap.
Q: Should I count both the start and end date?
A: This tool gives the straightforward subtraction between two dates. Contracts using inclusive counting, which counts both endpoints, would add one extra day to this result.
Q: Do leap years affect the day count?
A: Yes — if the range spans a leap year's February 29, the count includes that extra day automatically.
Q: Can I calculate the difference between dates years apart?
