Update date column and copy value from a different date column only once

Hi,
Looking for a way to update column date and copy date from a different date column only once.

Not sure if it’s automation (preferably) or formula,
but the scenario is that column date 1 is not necessarily being created with a date value, but when it does being updated with one,
I want to copy it over to the other date column for tracking and comparison purpose (original date vs most recent date).

Hope this was clear enough, thanks in advanced.

Same issue here! But also I need to copy date created by a formula, to a regular date column. This is because Start + End = Timeline app does not recognise end time from a formula column. Thanks!

Hi @Marcelo_BCN - Have you checked out General Caster? You can use formulas and cast the result to standard columns. There is a free tier depending on your usage.

Thanks
