Convert Week Number to Date

I’m hoping for a way to convert week number to month and day.

I got the week number by using"%W") --Returns 15 because we're in the 15th week of 2022

But now I would like to convert the week number to time in seconds similar to what os.time() returns.

year=2020, month=4, day=15, -- Date components
hour=16, min=28, sec=0 -- Time components
})) --> 1586968080

The problem with this is that it doesn’t take in week number so I need to somehow calculate the month & day based on the week number and then plug that into os.time().

Well a week is always 7 days, soooo:
day = week * 7
