How the Half Birthday Calculator Works
A half birthday is the day exactly six months from your birthday — popular for kids with birthdays near major holidays, and a fun excuse to celebrate mid-year. This calculator adds six months to your birth date and shows the resulting date, the day of the week it lands on, and how many days away the next one is.
If your birthday is on the 15th of a month, your half birthday is the 15th of the month six months later. The calendar handles the month and year rollover automatically.
half birthday = birthday + 6 months
