Day-of-Year Calculation in Excel/Google Sheets
Formula 1: Day of the Year for Today
=TODAY()-DATE(YEAR(TODAY()),1,0)
Copied
- TODAY() returns 3/16/2025.
- DATE(YEAR(TODAY()), 1, 0) returns 12/31/2024 (day 0 gives the last day of the previous year).
- Subtracting gives: 3/16/2025 – 12/31/2024 = 75.
Formula 2: Day of the Year for a Given Date
=B2-DATE(YEAR(B2),1,1)+1
Copied
- Suppose B2 has July 4, 2023
- DATE(YEAR(B2),1,1) returns January 1 of that same year, so July 4, 2023, it returns 1/1/2023
- Subtracting gives: 01/01/2023 from 07/04/2023 = 184
- Since January 1 should be day 1, you add 1. So it is the 185th day of the year
Formula 3: Get Date from a Day Number
=DATE(2023,1,0)+C2
Copied
- DATE(2023,1,0) returns December 31, 2022
- C2 has the number 150
- When you add 150 to December 31, 2022, the result is May 30, 2023.
