Date Formula: how to get a Monday Date based on Week number

[Michael_Leidens]

Hi,
In column A, I listed all weeks number (from 1 to 52)
in column B, I would like to have the correspondant date based on Monday.

ex in 2021
Column WEEK: 52
Column Day = Monday 27th dec.

How to set up this in airtable?
thank you

Hi @Michael_Leidensdorf ,

You can use the following function:

DATETIME_PARSE({number_of_week },'W')

using the capital , the function datetime_parse returns the corespondent date of on Monday as it follows the ISO specifier
