Calendar - Jewish Holidays End in 2026

Hello @Daniel Pilarski

At this time, there is no public confirmation from Microsoft that the built-in Jewish holiday calendar used by Classic Outlook for Windows will be updated beyond 2026.

Multiple users have reported that Jewish holidays stop appearing after 2026, and the behavior is consistent with reports that the built-in holiday data currently ends in 2026.

Because it's important fo you, as a workaround, you can try to subscribe to an online Jewish holiday calendar, such as Hebcal. This calendar is maintained separately from Outlook's built-in holiday list and continues to provide future holiday dates automatically.

For example, you can subscribe to the Hebcal Jewish holiday calendar:

• Open the Hebcal calendar page: https://www.hebcal.com/ical/

• Choose the Jewish holiday calendar you want, copy the suitable link.
• Follow the Outlook subscription instructions provided by Hebcal.
• The calendar will appear under Other Calendars/My calender in Outlook and can be viewed alongside your primary calendar.
