Hi all,
I have a simple question (tried googling but found no answers). How do I
convert weeks elapsed into months elapsed?
I have data that contains duration in weeks (without any other date
values such as year and so on) for example a week value of 14 and I
would like to convert the 14 weeks to 3 months (some lose of accuracy
expected).
Expected tests may be:
14 weeks yields 3 months.
1 weeks yields 0 months.
Is there such a function. The rudimentary solution (may reduce lose of
accuracy) am thinking of is to add the weeks to the value returned by
clock_timestamp() then subtract clock_timestamp() from it. The question
now is how to convert the returned value to months elapsed as opposed to
days elapsed.
Allan.
