Google Calendar now supports several new features:
– When scheduling appointments, you can now automatically find the next available time that works for all attendees and resources like conference rooms.
– You can add a secondary time zone to see when events take place if you frequently travel between time zones or work with people in other time zones.
– Meeting reminders can now be customized more granularly between zero and five minutes before an event.
– Google Calendar supports more keyboard shortcuts now.

How to access what's new:
To have Google Calendar find the next available time for a meeting, click 'Create Event' and then 'Check guest and resource availability'. Add the invitees and resources (like conference rooms) you want to invite, set the duration of your meeting, and click 'Find next available time'.

To add a secondary time zone, click 'Settings' and then 'Show an additional time zone' to make a time zone selection that will appear on your calendar alongside your primary time zone.

Granular meeting reminders can be set per-event by clicking 'Event details' and adjusting your preferences.
