Lable YTD Rows in Calendar

The formula will return true for each of those dates.

The following M code generates all dates from 1st Jan 2020 to 31st Dec 2023 and uses the formula to mark each date as in YTD or not so you can check if it does what you want. The screenshot in your question was not readable so maybe there's some other subtlety in the question that it would reveal.

let
Source = List.Dates(#date(2020,1,1), Duration.TotalDays(#date(2023,12,31) - #date(2020,1,1)) + 1 , #duration(1,0,0,0)),
#"Converted to Table" = Table.FromList(Source, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
#"Changed Type" = Table.TransformColumnTypes(#"Converted to Table",{{"Column1", type date}}),
#"Renamed Columns" = Table.RenameColumns(#"Changed Type",{{"Column1", "Date"}}),
#"Add in Year" = Table.AddColumn(
   #"Renamed Columns", 
   "Error Free Version", 
   each Date.IsInYearToDate( 
   Date.AddYears( [Date], Date.Year(DateTime.LocalNow()) - Date.Year([Date]) )
   ),
   type logical
   )
in
#"Add in Year"
