About this days between dates calculator
This free calculator counts the exact number of days between two dates, and also shows the result in weeks. Choose a start date and an end date, and the answer updates instantly in your browser. It is useful for counting down to an event, working out how long ago something happened, tracking deadlines, or planning trips and projects.
The calculation correctly accounts for different month lengths and leap years, so the count is accurate rather than an estimate. The order of the dates does not matter — you always get the positive number of days between them. Nothing you enter is uploaded or stored.
How to use it
Tap the start date and end date fields, pick your dates, and read the number of days and weeks between them. Change either date any time to recalculate.
