Neerav:
Since you don't have the day, you need to assume it.

So, if you have some code to hand that uses MDY, just assign a 1 for all
the days.

Alternatively, calculate age by subtracting birth year from current
year, and then subtract 1 if birth month is greater than current month.

Or am I missing something?
