Baby’s full month calculated with 4Dec to 4th Jan only.. are you referring to days to be calculated?
Full month will be 4th Jan. 12 mth will be 4th Dec 2023, which is the baby 1 year old birthday!
For me, I just count the same date. Meaning 4th Jan, 4th feb etc.
I go by the number of days, Day 30 = full month in my case.
Here to know something interesting !!
