Days Between Dates
Free days between dates calculator: count the days, weeks, and months between two dates, with a full years-months-days breakdown.
Pick two dates
Choose a start and end date to see how far apart they are. The order does not matter.
Days between counts full days from the start to the end date. Including the end day adds one, which is how billing and rental periods are often counted.
How the days are counted
The calculator turns both dates into days and subtracts one from the other, so the result is the number of full days between them. Because a date has no time of day here, the count is the same whichever order you enter the dates.
Some counts include the end day and some do not. A stay from the 1st to the 4th is three nights but four days if you count both ends, so the tool shows both the plain difference and the inclusive count.
Days between dates questions
Does the count include the first and last day?
The main result counts full days from the start to the end date, so it does not include the start day itself. The "including the end day" figure adds one, which matches how nights, rentals, and billing periods are often counted.
How many weeks are between two dates?
The tool shows a weeks-and-days split of the total: it divides the day count by seven for the whole weeks and shows the leftover days beside it.
How do I count only working days?
This tool counts every calendar day. To exclude weekends and public holidays, use the working days calculator instead.
