Birthday Countdown
Count down the days to your next birthday and see the day of the week.
Your birthday is the one date you never want to miscount, and "how many days until my birthday?" deserves a precise answer — especially when planning a celebration or just enjoying the anticipation. The tricky part is that once this year's birthday has passed, the countdown rolls over to next year.
Enter your date of birth and this tool counts the days to your next birthday, tells you which day of the week it lands on, and how old you'll be turning. It handles the year rollover automatically, so the number is always for the upcoming birthday.
