Hello Everyone,

I am looking to convert date to weeks
variable is daterec and the range is from (08jan2008 - 31dec2018)
I have converted to months (1 - 132)
but now I am looking to convert to weeks.
I am unsure how STATA determines weeks.

some insight would be much appreciated !

Here is a section of the data.
