Day Counter
This day counter works out how many days there are between two dates, as plain days, weeks and days, and years, months and days. Choose whether to count both dates or just the days between. It also counts business days, leaving out the weekend (Saturday and Sunday, Friday and Saturday, or Sunday only) and, if you like, US federal holidays or UK bank holidays. To find a date instead, add or subtract days, weeks, months or business days from any date. Dates run from 1900 to 2100, and you can download every day in the range as a CSV.
100% private — everything runs in your browser. The counts are worked out on your device; nothing is uploaded.
Days between two dates
Business days
Add or subtract
Everything runs in your browser and only your settings are remembered in this browser. Business days leave out the weekend you choose and, if you pick a table, public holidays: US federal holidays with their observed days for 2026–2034 (Office of Personnel Management schedules to 2030, then the rules in 5 U.S.C. 6103) and UK bank holidays for 2026–2028 (GOV.UK). Outside those years only weekends are left out. State, local and company holidays are not included.
How to count days between dates

How the days are counted
Days between = end date minus start date. Include both dates = one more. Weeks and days split the same total. Years, months and days add whole months to the start date (on a shorter month, its last day) and count the days left. Business days are counted over the same days, leaving out the weekend you choose and any public holiday on a weekday. The tool was checked against a separate date calculation for every date from 1900 to 2100.

Does the day counter include the end date?
Choose. “Days between” is end minus start: from 1 January to 2 January is 1 day. “Include both dates” adds one, counting the first and last day, as when counting the days of a trip: 1 to 2 January is 2 days.
How many days are there between 1 January and 31 December 2027?
364 days between them, or 365 counting both dates (2027 is not a leap year).
How many business days are there in 2027?
261 weekdays. Leaving out the US federal holidays that fall on weekdays (and their observed days) gives 249; England and Wales bank holidays give 253.
What date is 90 days from 1 January 2027?
1 April 2027. Add or subtract days, weeks, months or business days from any date.
What does adding business days do?
It moves forward one working day at a time, skipping weekends and the holidays you chose; the start date itself is not counted. 10 US business days after Friday 18 December 2026 is Tuesday 5 January 2027 (Christmas and New Year’s Day are skipped).
What is one month after 31 January?
28 February 2027 (29 February in a leap year): when the month is shorter, the answer is its last day.
Which holidays are included?
US federal holidays with their observed days for 2026–2034, and UK bank holidays for 2026–2028 for England and Wales, Scotland or Northern Ireland, as GOV.UK publishes them. Outside those years only weekends are left out, and the tool says so. State, local and company holidays are not included.
How far back can I count?
Any date from 1 January 1900 to 31 December 2100.
