"twitter:image": "https://calendarbest.com/og-image.png" "twitter:title": "Days Between Dates Calculator | CalendarBest" --- > Index of every page on this site: [llms.txt](https://calendarbest.com/llms.txt) Choose a start and end date to count the days between them. ## **How the days are counted** The calculator counts every calendar day from the start date up to, but not including, the end date. That matches how you would say "it is 7 days from Monday to next Monday". Tick **Include the end date** when both days count, such as the length of a holiday or a project that runs to the end of its last day. Weekdays are Monday to Friday. US working days also leave out the [federal holidays](https://calendarbest.com/holidays) on their observed dates, so a holiday that falls on a Saturday removes the Friday before it. Open the list under the result to see which holidays were skipped. ## **Worked examples** | Dates | Days | Working days | | --- | --- | --- | | [Jan 1, 2027 – Dec 31, 2027](https://calendarbest.com/tools/days-between-dates?from=2027-01-01&to=2027-12-31&end=1)All of 2027, both dates included | 365 | 249 | | [Jan 1, 2028 – Dec 31, 2028](https://calendarbest.com/tools/days-between-dates?from=2028-01-01&to=2028-12-31&end=1)2028 is a leap year, so it has one extra day | 366 | 250 | | [Nov 1, 2026 – Dec 25, 2026](https://calendarbest.com/tools/days-between-dates?from=2026-11-01&to=2026-12-25)From 1 November to Christmas Day | 54 | 37 | | [Jan 4, 2027 – Apr 1, 2027](https://calendarbest.com/tools/days-between-dates?from=2027-01-04&to=2027-04-01)A first quarter of work, starting on a Monday | 87 | 61 | ## **Days Between Dates FAQ** ### **How do you calculate the number of days between two dates?** Subtract the earlier date from the later one, counting the start date but not the end date. From January 1 to January 31 is 30 days. If you want both dates counted, as for a hotel stay or an event that runs on both days, add one day: January 1 to January 31 inclusive is 31 days. ### **Does the calculator count the start date and the end date?** By default it counts the start date and stops before the end date, the same way most date calculators and spreadsheets do (=B1-A1 in Excel). Tick "Include the end date" to count both. ### **How are working days counted?** Working days are Monday to Friday, minus US federal holidays on the day they are observed. When a holiday falls on a Saturday it is observed on the Friday before; on a Sunday, the Monday after. State holidays and company closures are not subtracted. ### **Do leap years and daylight saving time change the result?** Leap years are counted: February 29 is a normal day in the range, so 2028 has 366 days. Daylight saving time does not change anything, because the calculator counts calendar days rather than 24-hour blocks. ### **How many days are there in a year?** A common year has 365 days and a leap year has 366. Leap years are divisible by 4, except century years that are not divisible by 400, so 2000 was a leap year and 2100 will not be. 2028 is the next leap year. ```json {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://calendarbest.com"},{"@type":"ListItem","position":2,"name":"Tools","item":"https://calendarbest.com/tools"},{"@type":"ListItem","position":3,"name":"Days Between Dates","item":"https://calendarbest.com/tools/days-between-dates"}]} ``` ```json {"@context":"https://schema.org","@type":"FAQPage","mainEntity":[{"@type":"Question","name":"How do you calculate the number of days between two dates?","acceptedAnswer":{"@type":"Answer","text":"Subtract the earlier date from the later one, counting the start date but not the end date.
