How it works
- Tap Generate for a random month and day.
- Turn on a year range if your birthday needs a year.
- Read the weekday, zodiac sign, birthstone and birth flower.
Every pick starts from your browser's cryptographic random number generator, so each option has the same chance unless you set a weight. How the randomness works.
Ways to use it

Questions people ask
What is the birthstone for each month?
The common modern list is garnet for January, amethyst, aquamarine, diamond, emerald, pearl, ruby, peridot, sapphire, opal, topaz and turquoise for December. Some months have more than one stone on other lists.
Does a random birthday come with a birth year?
Only when you turn on the year range. Then the tool picks a year inside your range and the weekday matches that exact date.
How is the zodiac sign worked out?
Each sign covers a range of dates, such as Aries from about March 21 to April 19. The tool checks which range the birthday falls in.
What is a birth flower?
Each month has a traditional flower, like carnation for January and rose for June. The tool shows the one for the generated month.
