Frequently Asked Questions

How do I calculate the number of days between two dates?
Enter a start date and end date and the calculator instantly shows the exact number of days between them, along with the equivalent in weeks, months, and years. It accounts for different month lengths and leap years automatically.
Does the calculator include or exclude the start and end dates?
By default, the count includes the end date but not the start date — this is the most common convention for measuring elapsed days. For example, from January 1 to January 3 is 2 days.
Can I calculate days between dates in the past?
Yes. You can enter any two historical dates and the calculator will work out the interval. This is useful for calculating how long ago an event happened, an age on a specific date, or how long a historical period lasted.
How many days are in a year?
A regular year has 365 days. A leap year has 366 days, with February 29 added. Leap years occur every 4 years (years divisible by 4), except for century years not divisible by 400. The average year is 365.2425 days.
How is the number of months between two dates calculated?
Months between dates count complete calendar months. For example, from March 15 to June 10 is 2 complete months (with 26 remaining days), not 3. The calculator shows both complete months and the remaining days.
Can I use this to calculate project durations or contract lengths?
Yes. Enter the start and end dates of your project or contract to see the total duration in days, weeks, and months. For business day counts (excluding weekends and holidays), use the Business Days Calculator instead.
