Strange behavior with Date Field Bulk Calculation in Arcgis Pro.

SITRAVENNA — Tue, 04 Mar 2025 08:38:24 GMT

With a date field set with DD/MM/YYYY format, in filegeodatabase, if I insert the date via calendar there is no problem, while if I calculate it via Calculate of PRO with a date > day 12, it inserts the date correctly; while if the date has a day less than twelve, it inserts the date in the MM/DD/YYYY format. Has anyone ever encountered this problem? And how did you solve it without having to force the calculation with Python every time?

Is there a difference in your locale's date setup on your computer vs what Pro uses?

Are you using a specific option to calculate dates in the field calculator? Look at some of the examples

no difference between pc local data and PRO. Will continue to use python expressions to avoid errors.

Thank Dan.

It would be helpful to share a specific example of text and code and the result. I can't say I completely understand the steps you are taking, so I can't offer any specific feedback.
