# Calendar Pro time zones
Calendar Pro shows every event in a single time zone so your team reads the same schedule. You can set the time zone for the whole shared calendar, or override it on a single event when you plan across regions.
# Change the time zone for the whole calendar
Use the calendar-level time zone when your channel works mostly from one region.

# Common questions
# Does changing the calendar time zone affect all participants?
Yes. Updating the calendar time zone applies to everyone in that channel, and events and holidays adjust automatically.
# What happens to existing events when I change the calendar time zone?
Events shift to the new time zone. An event set at 10:00 AM, for example, then displays at the equivalent time in the new zone.
# Can I display more than one time zone at once?
No. The calendar view shows one active time zone at a time. You can still give individual events a different zone when you need to.
# Will public holidays update when I change the time zone?
Yes. The public holiday list refreshes automatically to match the region linked to the new time zone. See set up and change public holidays for more.
# How should I handle a team spread across time zones?
Keep the calendar on your main team time zone, and set the event-level time zone only for specific cross-regional meetings. This keeps the schedule clear for everyone.
