,Hi AzureMilk

Good day, and thank you for providing the details of your issue.

I tested this on my end and found that holiday data has been updated for some calendars, while others still appear to be missing certain entries. For example, I noticed that some Jewish Religious Holidays for 2027 are not currently available, while many other holiday calendars appear to have been updated already. This suggests that some holiday datasets may still be in the process of being updated.

Upon further research, I also found that other users have reported similar concerns regarding built-in holidays missing for 2027 and beyond. As such, I would encourage you to add your vote and feedback to the existing feedback item below to .help increase visibility with the product team: built-in holidays missing for 2027 and beyond

Please note that, as an Independent Advisor, I do not have direct access to Microsoft engineering teams or the ability to influence product updates.

I understand this may be inconvenient, especially when planning calendars well in advance, and I appreciate you taking the time to report it.
