This was a great help. I always have to search internet to figure out how to convert these. Now, I’ve created functions and will no longer have to do that.

In case you have a 0 in the Julian date field(wrong sqls or anything) its good to have the following sql
decode(DATEVAL,0,’0′,TO_DATE(1900000 + DATEVAL, ‘YYYYDDD’))

Deepesh ,

Was nice to get your website as the first one on my google search. Keep it up.. good work

You can edit the content to also show a reverse conversion to convert oracle system date to Julian (basically just reverse of the logic to convert to Julian)

TO_NUMBER(TO_CHAR(SYSDATE, ‘YYYYDDD’))-1900000

Hi,
Could you please tell me where in access I would need to put this below code, to convert the date from julina to gregorian?

19 + SUBSTR( DATEVAL , 1, 1 )
|| SUBSTR(DATEVAL, 2,2)
|| ‘/’
|| TO_CHAR( to_date( SUBSTR( DATEVAL, 4, 3 ) , ‘DDD’) , ‘MM’ )
|| ‘/’
|| TO_CHAR( to_date( SUBSTR(DATEVAL, 4, 3 ) , ‘DDD’) , ‘DD’ )

Thanks in advance
