Can anyone help me convert a backwards formatted Julian date code? For example 25922 is September 16th, 2022.

Hi, DT, try below formula:
=DATE(IF(0+(RIGHT(A1,2))<30,2000,1900)+RIGHT(A1,2),1,LEFT(A1,3))
then format the result as the date formatting as you need.

Sunny-
Thanks for the reply, in order to get a 4-digit number, I last digit of the year would suffice (i.e. 2022=2 or 2023=3).
If you have any other ideas on how to modify the formula let me know...and thanks again for your response.

Hi, Tony, try this formula =RIGHT(TEXT(I1,"yy")&TEXT((I1-DATEVALUE("1/1/"&TEXT(I1,"yy"))+1),"000"),4), I1 is the date you want to convert.

Hi-
Thank you for the excel formula...that converts a Calander date to a Julian date =TEXT(A1,"yy")&TEXT((A1-DATEVALUE("1/1/"&TEXT(A1,"yy"))+1),"000")

Your formula displays 5 digits for the Julian date....I'd like to change in the formula to get 4 digits for the Julian date. What should I do to get this outcome?

Thanks

Tony

Hi, Tony, the formula TEXT(A1,"yy")&TEXT((A1-DATEVALUE("1/1/"&TEXT(A1,"yy"))+1),"000") returns a 5-digit number, first two number indicate the year, last three number indicate the nth day of the year, 5 numbers combined to indicates the date. If you just want 4-digit number, I do not know which number you want to ignore.

Good Afternoon Sunny, I am in the same boat as Tony - Where I work we use a 4 digit Julian code, not a 5 digit one. For example - 29 December, 2023 would be listed in my work systems as Julian date "3363" instead of "23363" and 26 September 2016 would be listed as Julian date "6270" instead of "16270". Would it be possible for you adjust your formula to reflect this?

Si tienes Office en español, puedes utilizar la siguiente formula =TEXTO(DE2,"AA")&TEXTO((DE2-FECHANUMERO("1/1/"& TEXTO(DE2,"AA"))+1),"000") donde DE2 es la celda donde esta tu fecha gregoriana. Saludos

Hi, there is a problem when you try to convert Julian date to calendar date with dates of 2001 thru 2009. Any suggestions? Example 1/1/2001 = JD of 01001 which is correct. However if you use the formula JD of 01001 to Calendar Date conversion the answer is 1/1/2010. Where is this error?
