How this count works
Pick the month and day of your birthday. The count goes to its next date, leaving today out and including the birthday itself. Add a birth year to see the age you will turn.
A February 29 birthday counts to February 28 in years without February 29, the same convention as the age calculator. What you enter stays in this browser unless you share the link.
For example
On September 19, 2026 in New York, a birthday on December 25 is 97 days away. That year it falls on a Friday.
