Try setting the two digit max year in locale preferences.

This is called the rollover date and it was a popular topic around the changing of the millennium.   

adxdcs is a pivot year used to determine the century when the year is two digits.

Upper and lower bound

You need to provide a pivot date to define the century used by default when the date is two digits. Only the upper bound is entered, the lower bound is calculated accordingly.

Example: If you enter 2029 for the upper bound:

• Any date with a year that has two digits lower or equal to 29 is in the [2000-2029] range.
• Any date with a year that has two digits between 30 and 99 is in the [1930-1999] range, which is the reason why 1930 > is displayed in the lower bound.

thanks! 

hi- i'm looking at the locale and see the two digit max year but I don't understand when you say upper bound and lower bound.  So what do I adjust so I can have the year default to 2030?  thanks

Just set the pivot year to 2050.   As long as you have no data in the system with 2 digits years prior to 1950 it will then start "pivoting" on 2050.   Birthdays can be a problem because folks born in 1949 with a 2 digit year entered would be born in 2049 but you would think that programmers would use a 4 digit year anywhere that exist. 

So editing the discussion above

Example: If you enter 2050 for the upper bound:

• Any date with a year that has two digits lower or equal to 50 is in the [2000-2050] range.
• Any date with a year that has two digits between 50 and 99 is in the [1950-1999] range

what is the trick to enter the "Two-digit max year " field?  I selected the pencil icon to enter the menu "edit" but that specific field will not allow me to update the value.  I can update other fields.  Thanks

My answer was too complex and including programmer stuff.  I find such stuff interesting and some other people might too.

Just set the pivot date.

Thanks - I found it.  I was one menu off.  The path to update the pivot date is: Administration>Administration>Settings>Global Settings (not actually in the "Locales" menu)

>>I was one menu off. 

I always am.... one menu off....

Jeremy,

Did you ever get an answer to this question? I am having the same issue with not being able to edit the two digit max year in Global Settings.

Dave

I did.  You have to change the upper bound pivot date. The path to update the pivot date is: Administration>Administration>Settings>Global Settings then click edit.

I figured it out...

Thanks!
