How to Sync Work and Personal Google Calendars
Work Google Calendar and personal Google Calendar do not talk to each other. They are different accounts. Overlaying one onto the other is free. Making the work calendar actually busy when you have a personal appointment takes a copy, and the copy is where people leak private titles into a company tenant.
The setup that works for almost everyone: one-way, personal → work, title rewritten to “Busy.” Coworkers stop booking you. The employer does not get the dentist, the recruiter, or the school pickup.
What each option actually does
| Method | Events live on | Work admin can see personal titles | Stops double-booking |
|---|---|---|---|
| Share personal → work, free/busy | Personal account | No (titles hidden; edge cases exist) | Sometimes — depends whether coworkers look at that overlay |
| Share personal → work, full details | Personal account | Yes | Yes, if they look |
| Subscribe via ICS | Source account | If you published details | Unreliable; refresh is slow |
| One-way copy, title = Busy | Both (copy is native on work) | No | Yes — the work calendar itself is busy |
| Two-way copy | Both | Yes, unless both sides rewrite | Yes, and work titles land on personal |
The important row is the one-way copy. The busy blocks are real events on the work calendar. Booking links, Find a time, and coworkers looking at your main calendar all see them.
The recommended setup: one-way Busy copy
Calendar Sync is built for this. Free, no signup to try.
- Connect the personal Google account and the work Google account.
- Source = personal primary calendar. Destination = work primary calendar.
- Title = Busy (or a template if you want a marker only you recognize).
- Strip attendees. Blank description and location.
- Show as Busy.
- Optional condition: if visibility is private, copy; if it is already a public personal event, you can let the real title through.
- Turn it on. Edits and deletes on the personal calendar follow.
Do not add a reverse rule that copies work events onto the personal calendar unless you want work meeting titles in the personal account. One-way is enough.
Overlay, if you only need a view
On the personal calendar: Settings and sharing → Share with specific people → add the work address → See only free/busy.
On the work account the personal calendar appears under Other calendars. Toggle it when you want the picture. Do not use See all event details into a work tenant.
This does not write events onto the work primary calendar. A coworker using Find a time on your work calendar may still see you as free.
Two-way, if you really want it
CalendarBridge and Reclaim will sync both directions. CalendarBridge Basic is $4–$5/month for two calendars. Reclaim Lite is free for one sync; Starter is $10/seat/month yearly for more.
Two-way is how work titles end up on the personal calendar and personal titles end up at work. Only do it if both sides rewrite to Busy, which is two one-way rules — at which point you are back to Method 1, twice.
What breaks
- Recurring events. A proper mirror updates the series. Export/import and a Zap that only fires on “new event” do not.
- Deletes and moves. Same problem. If the tool does not watch for them, the work calendar keeps a ghost busy block.
- Declined meetings. Decide whether a declined personal invite should still block work. Usually no.
- Private events. Google’s private flag is not a security boundary once the event has been copied or shared with details. Rewrite the title yourself.
- Working hours and focus time. Those live on one account. They do not cross. Set them on work. Let the Busy copy handle personal time.
What not to do
Do not merge the accounts. Google will not, and forwarding invites makes you a guest of your own life.
Do not import a full personal ICS into the work calendar. That is a one-time dump of real titles into the company account.
Do not put the personal calendar on a company-managed phone profile if that is how the company backups calendars.
If you also want an assistant
Sync keeps the work calendar honest. It does not propose times or send the email. Carly connects both Google identities, checks both calendars, and creates the event on the one you name. Free Zapier-style workflows; AI agents from $35/month.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
