How the date difference calculator works
This tool calculates the exact number of days, weeks, months and years between two dates, accounting for leap years and the correct number of days in each month.
Besides the total number of days, it shows a breakdown of weekdays (Monday to Friday) and weekend days (Saturday and Sunday), useful for planning deadlines, contracts and trips.
Frequently asked questions
Does the calculator account for leap years?
Yes. The calculation uses the real calendar dates, including February 29th in leap years.
Can I calculate the difference with the end date before the start date?
Yes. The tool automatically detects which date is earlier and shows the difference correctly, indicating whether the result is in the past or the future.
How are weekdays counted?
Weekdays are all the Monday-to-Friday days within the range between the two dates. National or local holidays are not taken into account.
Does the result include both the start and end day?
The total number of days represents the span between the two dates (end date minus start date), without counting the same day twice.
