About this birthday countdown tool
This birthday countdown tool shows both your next and previous birthdays relative to today. If your birthday is today, the next birthday calculator reads 0 days and the progress bar is full. For people born on February 29, the birthday is treated as February 28 in common years — that matches how most people celebrate and keeps the days until birthday count accurate. It’s the easiest way to answer “when is my next birthday?”
What you’ll see after calculating
- Next birthday date and weekday
- Days remaining with a visual progress bar
- Previous birthday date
- Current age in years, months and days
- Zodiac sign and the weekday you were born
