You can figure out half birthday by using two slightly different methods:
Add 6 months to your actual date of birth
For Example, If you were born in February, your half birthday will arrive in August.
Add 183 days to your date of birth
For Example, If you were born on March 15, adding 183 days puts your half birthday around September 10th.
We have arranged a chart below by which you can estimate exactly the date half of your birthday.
