How this is calculated
Today is day 0, and counting starts tomorrow. From Thursday, October 22, 2026, 30 days ahead is Saturday, November 21, 2026 and 30 days back is Tuesday, September 22, 2026. A deadline “within 30 days” usually ends on that date.
A week is 7 days. A month lands on the same day number in the later month. If that day does not exist, the date moves to the last day of the month: January 31, 2027 plus 1 month is February 28, 2027. That is why 1 month and 30 days are not always the same.
Business days are Monday through Friday without the 11 federal holidays in 5 U.S.C. 6103. A holiday that falls on a Saturday is taken off on the Friday before, one on a Sunday on the Monday after, as on the OPM schedule. 10 business days from Thursday, October 22, 2026 is Thursday, November 5, 2026, 14 calendar days later, because two weekends are skipped. State and local holidays, and the days off of a particular bank or court, are not counted.
The date in the box is the date on your device. Before the page has loaded, it shows the date in New York. For a span between two dates of your own, use the days calculator; to add years, months and days at once, the date calculator.

Questions people ask
Is today counted as day 1?
No. Today is day 0, so 1 day from today is tomorrow. If a rule counts today as day 1, enter one day less.
How do I count 90 days from a date?
Pick the date as the start, enter 90 and choose Days. From October 22, 2026, 90 days later is Wednesday, January 20, 2027.
What is the difference between days and business days?
Days count every calendar day. Business days skip Saturdays, Sundays and federal holidays: 10 business days from October 22, 2026 is November 5, 2026, 14 calendar days later.
How are months from today counted?
A month keeps the day number, so October 22 plus 3 months is January 22. If the day does not exist in that month, the date moves to the month's last day: January 31, 2027 plus 1 month is February 28, 2027.
How many weeks is 90 days?
12 weeks and 6 days. Divide by 7: 90 ÷ 7 is 12 with 6 left over.
Which holidays are skipped for business days?
The 11 federal holidays: New Year's Day, Martin Luther King Jr.'s Birthday, Washington's Birthday, Memorial Day, Juneteenth, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving and Christmas. A holiday on a Saturday is taken off the Friday before, on a Sunday the Monday after.
