Google Calendar sync guides
Resync mirrors busy time between Google calendars as privacy-preserving Busy holds. These guides cover syncing accounts, sharing availability without event details, and fixing common Calendar problems.
Sync & multiple accounts
- How to sync two Google Calendars
Share A's calendar onto B as an overlay. That does not block B for others. Resync writes Busy holds across Google calendars from different accounts.

The Calendar app can show several signed-in accounts together. Web Calendar is one account per tab. Seeing both does not block others. Resync writes Busy holds.
- Add your work calendar to personal Google Calendar
Share the work calendar with personal Gmail if your admin allows it, subscribe by URL, or keep both blocked with Resync Busy holds. No event details.
- How to merge Google Calendars
Google Calendar has no one-click merge. Overlay calendars, import events once, or keep them separate and sync private Busy holds with Resync.
- Copy events from one Google Calendar to another
Copy one Google Calendar event, export and import all events, or keep copying busy time. Import is a snapshot. Resync writes private Busy holds.

Busy time, privacy & availability
- Show busy on another Google Calendar
Google's free/busy share is a view, not a block on the other calendar. Resync writes private Busy holds so booking tools see you as busy.
- Show busy instead of details
Use Default, Public, or Private on an event, or share with See only free/busy. That hides details on one calendar. Resync writes Busy holds on another account.
- Avoid double booking Google Calendars
Sharing is a view, not a block. Manual Busy events and working hours stay on one calendar. Resync writes Busy holds so others see you as busy.
- Make Google Calendar events private
Set one event to Private so others see Busy. There is no switch that makes every existing event private. Resync writes Busy holds onto other calendars.

Busy occupies the time. Free does not. That is not Private or See only free/busy. Other accounts stay invisible. Resync writes private Busy holds.

Show your Google Calendar availability and check others'. Share free/busy, Find a time, or send a bookable link. Resync writes private Busy holds.
- Calendly double booking: why it happens
Calendly only checks calendars you connect for conflicts. A second account or Free event can double-book you. Fix it there, or write Busy holds with Resync.
