The day count is the number of nights from the earlier date to the later date. Ticking “inclusive” adds one, which is how you count every calendar day in a span (such as a trip or event) rather than the gaps between them.

What this days between dates calculator does
This days between dates tool counts the number of days from one date to another, and shows the same span as weeks-and-days, total weeks, approximate months, and years-months-days. It handles leap years automatically.
How the day count works
Days between = later date − earlier date (whole days)
Inclusive count = days between + 1 (counts both endpoints)
From 1 January to 31 December 2025 is 364 days; counting both endpoints (inclusive) gives 365.

Days Between Dates FAQ
How many days are between two dates?
Enter both dates and the calculator subtracts the earlier from the later to give the whole-day count — for example, 364 days from 1 Jan to 31 Dec 2025.
Does it count both the start and end day?
By default it counts the gaps (nights). Tick the inclusive option to count both endpoints, which adds one day to the total.
Does it handle leap years?
Yes. It uses real calendar dates, so leap days and varying month lengths are handled automatically.
Can the dates be in any order?
Yes. If the "to" date is earlier than the "from" date, the result is shown as a negative number of days.
How is the result shown in weeks and months?
Alongside the day count you'll see weeks-and-days, total weeks, approximate months, and an exact years-months-days breakdown.
Is the days between dates calculator free?
Yes, it's completely free, needs no sign-up, and gives instant results in your browser.
