## About

### Count the time between any two dates

Pick a start and end date and this calculator shows the exact number of days between them, plus the same span expressed in weeks, months and a years-months-days breakdown. It's perfect for counting down to an event, working out an age or anniversary, or measuring a project's duration.

### Business days and inclusive counts

A separate business-days figure counts only weekdays, which is useful for delivery windows, contracts and deadlines. Toggle 'include the end day' when you want both endpoints counted, such as billing periods or holiday lengths. All calculations run locally in your browser.
