What is a Birthday Calculator?
A birthday calculator is a tool that helps you determine exactly how many days remain until your next birthday. It calculates the countdown from today's date to your upcoming birthday, showing results in days, weeks, months, and even hours.
Beyond the countdown, our calculator also reveals interesting information about your birthday, including your zodiac sign, birthstone, and what day of the week your next birthday falls on.
How It Works
Days Until Birthday = Next Birthday Date - Today's Date
The calculator automatically determines your next birthday by checking if this year's birthday has passed. If it has, it calculates the days until next year's birthday instead.
Common Uses
- Planning birthday parties and celebrations
- Setting reminders for upcoming birthdays
- Counting down to milestone birthdays (18, 21, 30, 50, etc.)
- Finding your zodiac sign and birthstone
- Determining what day of the week your birthday falls on
