- "Count from" defaults to today's date, but can be changed to see the countdown as of any other reference date.
Frequently asked questions
What happens if the target date has already passed?
The result shows a negative day count and a "days ago" status instead of "days remaining".
Is there a version of this for a specific event or a birthday?
Yes — see the Event Countdown Calculator (same math, event framing) or the Birthday Countdown Calculator, which automatically finds the next occurrence of a recurring birth date.
Can I see the countdown as of a date other than today?
Yes — change the "Count from" field to any reference date.
