How Many Days Until My Birthday?
Enter the month and day of a birthday to see how many days are left. The birth year is optional and only used to show the age being reached. Nothing you enter is stored or sent.

We find the next occurrence of the birthday on or after the Count from date and count calendar days to it. The Count from date is not counted and the birthday is, so on the birthday itself the answer is 0.
Example: counting from November 9, 2026, a December 25 birthday is 46 days away on a Friday; a November 8 birthday is 364 days away.

The calculation happens in your browser. The month, day and year you enter are not sent to us, saved or used to set cookies. This page is meant to be safe for families, so any advertising added to it later will be contextual only.
Why a birthday moves one weekday each year
A common year has 365 days, which is 52 weeks and 1 day, so a date falls one weekday later next year. After a leap day the year has 366 days, which is 52 weeks and 2 days, so the shift is two weekdays.
Worked example: December 25, 2026 is a Friday. In 2027 it is a Saturday (one weekday later). In 2028, a leap year, December 25 is a Monday, because 2028 has a February 29 before it and so the shift from 2027 to 2028 is two weekdays.
February 29 birthdays
In years with no February 29, some places treat the birthday as February 28 and others as March 1. We default to February 28 and let you choose. This is a counting convention for this page, not a legal statement. For example, counting from November 9, 2026, a February 29 birthday falls on February 28, 2027, which is 111 days away, or 112 days with the March 1 choice.

Why does it ask for a birth year?
Only to show the age you will turn. Leave it blank and the age row stays hidden; the day count does not change.
