Days Between Dates Calculator
How many days are there between two dates? Enter a start and an end date to get the number of days, weeks, months and years, and the count of weekdays (Monday to Friday) in between.
- Days, weeks, months
- Weekdays counted
- Include end date option
- No sign-up
How to use
- Pick the start date and the end date.
- Tick Include the end date if both days should count (for example a 5-night hotel stay counts 5, a 5-day event counts 6).
- Read the total days, weeks and days, and the years, months and days.
- Use the weekday count for a quick business-day estimate (public holidays are not removed).
How the difference is counted
The calculator counts the full days from one date to the next, so 1 June to 2 June is 1 day. If you include the end date, the same range is 2 days. Years, months and days follow the calendar, so the numbers match what you expect when counting from, for example, 15 January to 15 April.
Weekdays and business days
Weekdays are Monday to Friday. The count does not remove public holidays because they differ by country, so subtract them yourself for a work-day total. Need someone's age? Use the age calculator.
Frequently asked questions
How many days are between two dates?
Enter both dates above. The first result line is the total number of days between them.
Does it include the last day?
Only if you tick "Include the end date". By default it counts the nights between the dates.
Does it count business days?
It counts weekdays (Monday to Friday) but cannot know public holidays in your country.
Can the end date be before the start date?
Yes. The result is the same difference, and a note tells you the end date is earlier.
