Age Formula
 

I have a formula that determines a child's age by the month. I noticed
that today 9/16 one of our children turned 1 month old but the answer
still says 0. What is wrong with formula.
It would be nice if I had one formula instead of two. THe formula can
calculate age up to 6 weeks, the in months from 2 months up to 35
months, and then 3 years and up. Can anyone help me?

This is the formula I use for the months
=IF(C87="","",ROUNDDOWN(((TODAY()-C87)/365*12),0))''=


This is the formula I use for the 3 year olds and higher.
=IF(ROUNDDOWN(((TODAY()-B9)/365*12),0)=37,ROUNDDOWN(((TODAY()-B9)/
365*12),0),ROUNDDOWN(((TODAY()-B9)/365),0))

It would be nice to have one formula to calculate all scenarios.

is there a code for weeks? year = "y", month = "m", day = "d". What is
weeks.

No code for weeks.

You can just subtract the birth date from today's date then divide by 7.

A1 = birth date

=(TODAY()-A1)/7

So I get that, but I don't understand how I can make the formula
determine my criteria
=(TODAY()-C87)/7
C87 is DOB
I want it to be IF(c87<8 weeks,then formula to calculate weeks, if(and
(c877 wks,c87<24 mo),"then formula to calculate months), if(c8723
months, then formula to calculate years)

I checked out DATEDIF but that does not calculate weeks. Can anyone
please help me with this formula. It needs to calculate daily. The
formula I had, did not calculate daily. Thanks!
