Hello, Klara,
2019-1-1 is Tuesday, it is working day.

If you want to exclude some holidays, such as New Year's day. you just need to apply the below formula:
=WORKDAY(DATE(YEAR(B2),MONTH(B24),1)-1,1,Holidays)
Note: Please change Holidays to the list of cell references which contain the holidays date.
