Hi  @Anonymous ,

Agree with @edhans , please use EDATE() to add years.

Or you could use Date.AddYears() to a custom column in Power Query:

Date.AddYears([Date],1)

And then change its type to Date. Below is the whole M syntax:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("VczBDYAwDATBXvxGOp+tJFBL5P7bIEiA4+c8ducUUyM66BLHKyo4Cp0fDSxyuKYaemJsl5URVxH/zp9nwtF2sKdOmETc", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Date = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Date", type date}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each Date.AddYears([Date],1)),
    #"Changed Type1" = Table.TransformColumnTypes(#"Added Custom",{{"Custom", type date}})
in
    #"Changed Type1"

Don't use DATEADD to add dates. This is a time intelligence function that creates a table of dates. To add days, just use +1 for one day. To add years, use the EDATE function.

EDATE('Table'[Column1], 12)

That will add 12 months to all dates and compensate for leap year.

Thanks so much for that, what formula could I use to add 2 years or more?

[edhans]

Just use increments of 12, So 12, 24, 36 for 1, 2, 3 years.

EDATE('Table'[Column1], 36)

would add 3 years.

See this article, as well as a bit of info on EOMONTH. EDATE – DAX Guide
