Frequently Asked Questions
How do I calculate the number of days between two dates?
Subtract the earlier date from the later date. Remember to account for leap years and different month lengths. Most spreadsheets and calculators can do this automatically.
What is a leap year?
A leap year has 366 days (February 29). It occurs every 4 years, except for years divisible by 100 -- unless also divisible by 400. So 2000 and 2024 are leap years; 1900 and 2100 are not.
What is the Day Calculator?
The day calculator computes the number of days between two dates or determines a target date after a given number of days.
How does the Day Calculator work?
Enter two dates to compute the difference in days, weeks and months. Alternatively enter a start date and a number of days to determine the target date. Weekends and holidays can be excluded.
