Starting in Spring ’24, Salesforce is enforcing the ICU Locale Formats instead of the JDK locale formats:

This migration can break existing code and installed packages, including Calendly integration with Salesforce:

Is Calendly integration with Salesforce fully compatible with the new ICU Locale Formats? Is there anything we need to do to prepare for this migration?

Hey @Sami41775!

Thanks for reaching out on this.

I was able to verify some information in regards to the ICU locale format change within Salesforce. Based on the information we have on the Calendly side of things, “Address, currency, date, date, time, integer, name, and time formats can change when a user changes locales. These formats can also change when the locale format standard changes or formats are updated.
 
It seems that this was first made available in 2020, so any instance created winter 2020 or later would have had the ICU locale format enabled by default. Based on our investigation on our end, however, this should not have any affect on your integration with Calendly and we have not seen it affect any of our other users at this time.
 
We do still recommend getting a secondary opinion from the Salesforce support team as they would have more insight from the product creation side of the integration.

Let me know if you have any other questions!
 


Thanks, David!
