Days Between Dates

Count the days between two dates in a simple popup. Works offline. No permissions.

Days Between Dates is a lightweight Chrome extension that helps users calculate the number of days between two selected dates directly inside the extension popup. The extension allows users to choose a start date and an end date and instantly see the day difference. Optional settings let users include the end date in the calculation or always display a positive result. The result is shown clearly and can be copied for reference. All calculations are performed locally in the browser. The extension works fully offline, does not access web pages, and does not connect to external services. No user data is collected, stored, or shared, and no special permissions are required. This tool is designed for quick and simple date calculations such as planning, tracking durations, or checking time gaps.
