About this countdown (days) calculator
This countdown tool calculates the number of full days between today and a target date. It can show how many days remain before an upcoming event (trip, exam, birthday, deadline) or how many days have passed since a date in the past.
The calculation is based on your local timezone: the tool normalizes both dates to midnight (00:00) before computing the difference, then rounds to whole days. This avoids “partial day” issues caused by the current time of day.
Everything runs locally in your browser (client-side). No dates are sent to a server and no data is stored by this page.
