Pick a target date to count the days remaining (or elapsed).
Days until a date gives you the plain number of days between today and any date, how many days until a future date, or how many days ago a past one was. No live ticking, just a clear count you can read at a glance.
For a real-time, shareable countdown to a precise moment, use the Countdown timer; to break a span into years, months and days, use Date difference. This tool keeps it to a single, honest day count, and a past date simply reports how many days ago it was.
Use Days until a date when you just want the number of days and no live clock, for example "how many days until the deadline". The Countdown timer is for a live, second-by-second display you can share.
