Pick a start date and an end date and this tool works out exactly how far apart they are. It breaks the gap down into full years, months and remaining days, the way you would naturally describe an age or a project length, and it also shows the raw totals: total days, weeks, hours and minutes across the whole span. That makes it handy for counting days until a deadline, measuring how long ago something happened, working out a rental or subscription period, or planning around a fixed date range. The calendar math accounts for different month lengths and leap years, so the numbers stay accurate no matter which months you cross. Everything runs locally in your browser, so your dates never leave your device.
