By the way, how do you calculate middle birthday when you have 3 favorites?

For example, let's say your birthday is January 2nd, favorite A's birthday is February 15th, and favorite B's birthday is January 20th.

First, convert all birthdays to days counted from January 1st.

Your birthday: 1 day

Favorite A: Days in January (31 days) + 15 days = 46 days

Favorite B: 20 days

Add all three numbers together to get 67 days, divide by the number of people (3) = 22 days (rounded), so January 22nd, the 22nd day counted from January 1st, becomes the three people's middle birthday ♡
