Why your birthday moves one weekday a year
A common year is 365 days: 52 weeks plus one day. So a birthday shifts forward one weekday each year, and two when a February 29 falls in between. That’s why a Friday birthday is followed by a Saturday one, and then often a Monday.
Questions people ask
How many days until my birthday?
Enter your birth date and the counter shows the days until your next birthday, the weekday it falls on and the age you are turning.
What if my birthday is February 29?
In years without a leap day, DayTrackr counts to February 28, which is the date most leaplings celebrate on. (Some prefer March 1; UK law, for example, treats March 1 as the legal birthday.)
How many sleeps until my birthday?
The same as the days shown, counting from tonight. The night before your birthday there is 1 sleep left.
