    Hi @Vineet S

    As far as I know, the Julian date is format as YYDDD, where YY means the two-digit form of the year and DDD means the DDDth day of that year.

    Just wondering what normal date you want to convert from 12490, because 490 clearly exceeds the maximum number of days in a year.

    Best regards,

    Cosmog

    simple expression:

    declare @j int = 24263; -- 2024-09-19 in Julian
select  dateadd(dy, (@j % 1000) - 1, dateadd(yy, @j/1000, cast('2000-01-01' as date)))
