The day of year calculator uses the number of days between the date of 1st january and the desired day. It takes into account the number of days in each month and can be set for a leap year.
Example: The 1st January 2021 is the day 1
Example: The 31th december is the 365th (for non-leap year)
|183th day (365/2)||02/07|
The calculation to be made is the date difference between the first day of the year and the current day.
A year has 365 or 366 days, the middle day of a year is the 183rd or July 2nd.
A calendar number is the (rare) name given to the day number in a year.
Type the formula =DATE(YEAR(TODAY()),1,A1) by replacing N with the day number to obtain the corresponding date in the current year. Replace YEAR(TODAY()) with any year value if needed.
