What is a Julian date?
In everyday use, a "Julian date" is the day of the year, numbered 001 to 365 in 2027. It is also called an ordinal date. ISO 8601 writes it as 2027-185 for July 4, 2027.
Some industries shorten it to a 5-digit code: the last 2 digits of the year, then the day number. In that form, January 1, 2027 is 27001 and July 4, 2027 is 27185.
Is a Julian date the same as the Julian calendar?
No. The Julian calendar is a different calendar system, introduced under Julius Caesar, and its dates now run 13 days behind the Gregorian calendar used in the United States. Some Orthodox churches still use it to set religious holidays. A day-of-year chart has nothing to do with it; the name is a leftover habit.
The astronomical Julian Day Number
Astronomers use the Julian Day Number, a continuous count of days that is 2,461,407 at noon on Friday, January 1, 2027. It never resets each year, which makes it useful for measuring long time spans.
How do I calculate the day of the year in Excel?
To calculate the day of the year in Excel or Google Sheets, use =A1-DATE(YEAR(A1),1,0), where A1 holds the date. Format the result as a number. Adding TEXT(…,"000") pads it to 3 digits.
