Boolean Dates is simply boss-speak for Julian Dates. There are probably 20 different ways "Julian Dates" can be encoded into an integer.

various ways I've seen "Julian Dates" have been encoded

1)	Days since a specific date (this date varies by implementation)
2)	first 2 digits are the year, the rest are days since Jan 1 of that
year
3)	first 2 digits are the year -- encoded as years since a particular
year
		the rest are says since Jan 1 of that year
4)	a combination of year (1st 2 digits), Quarter (2nd digit), Month

within the Quarter (3rd digit) and day of month (last 2 digits)

Good look!

Hi to all!

We have an old app that manages something that my boss calls: boolean dates.

He told me that exists an algorithm that manages dates as a boolean format.

We have several tables in this form:

Note: The following table: PAAM
has the field BDATE defined as NUMBER.

sql> select bdate from paam
sql> where rownum < 6

BDATE

728464
728434
728403
728495
728283

now, I need to convert that format to an 'understandable' format to get the old data and old dates.

I'm looking (google-ing) for that subject but, without luck.

any ideas? help?, pls...

Thanks in advance

Regards!
JL
