How Date Calculators Work
All date calculations on this site use the proleptic Gregorian calendar, the international standard adopted by virtually every country. The Gregorian calendar was introduced in 1582 to replace the Julian calendar, which had accumulated a 10-day error due to an imprecise leap year rule. Today’s system adds a leap day every 4 years, except for century years — unless the century year is divisible by 400 (so 2000 was a leap year; 1900 was not).
According to NIST’s time and frequency division, all official U.S. timekeeping is maintained using Coordinated Universal Time (UTC). Our calculators use your browser’s local date, which is synchronized to UTC through your operating system’s time service.
For business and legal purposes, the U.S. Department of Labor defines a “workday” as any day an employee performs work — typically Monday through Friday, excluding federal holidays. When calculating business deadlines, always verify whether the count includes or excludes weekends and public holidays.
Frequently Asked Questions
A date calculator is a tool that computes the number of days between two dates, or finds a future/past date by adding or subtracting days from a starting date. They are used for deadlines, countdowns, pregnancy due dates, project planning, and legal timeframes.
A standard year has 365 days. A leap year has 366 days, with the extra day added to February. Leap years occur every 4 years (e.g., 2024, 2028), making the average Gregorian year 365.2425 days long.
Use the “Days From Today” calculator at the top of this page — enter 90 and click Calculate. The result updates daily based on today’s date. You can also bookmark this page and return any time for an instant answer.
Use the “Days Between Dates” tab in the calculator above. Select your start and end dates and click Calculate. The formula is: End Date − Start Date = Number of Days. The calculator handles leap years and different month lengths automatically.
Our standard date calculators count all calendar days including weekends and holidays. For business-day-only calculations (Monday–Friday, excluding federal holidays), use a dedicated business day calculator or subtract the number of weekends manually.
