Using DATEADD with full date table - 1900 to 9999

[Staregirl]

Hi all

I am trying to use DATEADD with my Date table, but my Date table runs from 01/01/1900 to 31/12/1999

So I think if I try DATEADD('Date'[Date], -1, YEAR), for example, it returns "An invalid numeric representation of a date value was encountered" because if you take one year away from 1900 you get 1899? Which isn't valid?

I feel like MAX and MIN may come into play.

Could be something else but I'm trying everything at this point!

Thanks!

@Staregirl , Try like

Date(year('Date'[Date])-1, month('Date'[Date]), day('Date'[Date]))

Sorry Amit but this does not answer my question 😞

Update - I created a VAR that was EDATE([MeasureForMaxDate], -12)

That returns 31/01/9998

However, if I add 12 months instead, it throws a 'result is too large or too small' error.

BUT if I do the same with the MIN date, it returns 01/01/1899 - which I thought should throw the same error but I guess it's still a 4 digit year?
