  • =DATE(2020,1,0)
  • =12/31/2019

Tip: if the day number is less than 1, it will subtract absolute number of days from the first day of the month.

  • B3-(DATE(YEAR(B3),1,0))
  • =3/12/2020-12/31/2019
  • =72

Note

If you want to get the Julian date in 4-digit year and 3-digit day number, please use below formula

=TEXT(B3,"yyyy")&TEXT(B3-DATE(YEAR(B3),1,0),"000")
