Date Format and using database in various countries

ARC
Hello all,

General question for back-end database that has numerous date fields where
the database will be used in regions that put the month first, and regions
that do not.

Should I save a date format in the table design, such as: mm/dd/yyyy?

What I've done for years is to store the date format in date fields, then on
the forms, based on their region, I would set the date formats on form_load
depending on their preference of mm/dd/yyyy or dd/mm/yyyy. To try to combat
confusion, I added a 3rd preferred date format of: mmm-dd.yyyy, where the
month will be 3 letter designations.

Just curious what others are doing that deal with a database that can be
used globally.

Many Thanks,

Andy

I have many customers in Australia and the UK, but the bulk in the US. After
numerous enquiries from Australian users with bizzare behavior using
dd/mm/yyyy, I did end up adding a date format option for either dd-mmm-yyyy
or mmm-dd-yyyy, and that, as you say, eliminates all doubt regarding the
date.

Australia!

We use the british system and cannot figure out why access uses the mm
\dd\yyyy format sometimes.

The way we always do vba is to use MMM where applicable.

That way there is no doubt as to the date...

This works against sql server as well so it is more universal than the
function to switch at date to the american format above.
No offense meant to Allen but just use format to make your month three
characters and life is easier!

e.g. format(MyDate() ,"dd-mmm-yyyy") works with no issues against any
system....fo r australian/UK users and even using format(mydate() ,"mmm-
dd-yyyy") for us systems works fine..

Note: the format - yyyy-mm-dd is one of the best for queries against
other databases - e.g. dbII or sql server......and most systems
shouldn't have an issue with this.....

I would suggest that you carefully reread the replies of Allen Browne
and Rick Brandt, and also the article Allen Browne linked to.

When doing dynamic SQL, mmm-dd-yyyy or dd-mmmm-yyyy are *not* safe
formats.

For instance, they will barf with the settings I use. In particular for
December (des) and October (okt).

Both the format given by Allen Browne mm\/dd\/yyyy and the format given
by Rick Brandt yyyy-mm-dd are safe (the latter is also called ISO 8601).

If your "bizarre behaviour" relates to the interface, the easiest is
what is also already suggested, don't use any format at all for bound
controls. That way, the operators will get the format of their
regionale.

Hi, i'm using visual foxpro 9 with a mysql 5 database, for direct access to my database i use navicat. In visual foxpro i've set my date format to dd-mm-yyyy, also i did this in navicat.

I have an applicatoin that works 100% perfect when running on a machine setup for English (United States), but when I change it to Spanish (Mexico), the dates start giving me fits. THe reason is USA is mm/dd/yyyy and mexico is dd/mm/yyyy. So, with the computer set to mexico, any standard CDATE function is going to return the date in the dd/mm/yyyy setting since that is what the computer is set to.

On my machine in the office I change the computer setting to English (UK) so the date format is dd/mm/yyyy instead of mm/dd/yyyy for US. This problem happens in either Access or SQL Server. In the database I have a table with Date/time column. The database is located on a machine that is set to dd/mm/yyyy also. When I enter date 7/1/08 (as in January 7, 2008), it stores it in the database as 1/7/08 instead of 7/1/08. Why is it like that...
