Keep your work and personal calendars in sync

Two calendars, one person, zero coordination

Your work calendar knows about your 10am standup and your 3pm client call. Your personal calendar knows about your dentist appointment and your kid’s recital. Neither one knows about the other, which is fine right up until your partner books the dentist for 2pm on the exact afternoon you already have back-to-back client meetings.

This isn’t a rare mistake. It’s the default outcome any time two calendars that describe the same person don’t talk to each other. You end up as the manual bridge between them, checking both before agreeing to anything, texting “let me check my other calendar” more often than you’d like, and occasionally failing to check in time.

Sharing your calendar with a partner or colleague doesn’t fully fix it, because it depends on someone remembering to look. Importing one calendar into the other as an .ics feed doesn’t fix it either, those feeds are often delayed by hours, so a meeting you just booked doesn’t show up on the other side until well after someone’s already tried to book over it.

Neither approach was ever meant to solve this. Sharing assumes a human in the loop who checks at the right moment. Importing assumes a delay nobody minds. A double-booking only needs one of those assumptions to fail once.

A connection you set up once

2calendars solves this with a single connection between your work and personal Google Calendars, synced in both directions, in real time. Book a client call at work, and within seconds your personal calendar shows that hour as “Busy.” Book the dentist on your personal calendar, and your work calendar shows the same thing in reverse. No merged calendar, no manual copying, just two independent one-way mirrors running continuously, each feeding the other an honest signal of when you’re taken.

This is the classic “set it and forget it” case: one connection, configured once, that just keeps working in the background. You’re not maintaining anything after the initial setup, no nightly refresh to trigger, no weekly reconciliation to do by hand.

Privacy by default, not by request

The reason this works for a work-personal pair specifically is the privacy default. Your employer doesn’t need to know your 2pm block is a therapy appointment, and your personal calendar doesn’t need your client’s meeting agenda. By default, a mirrored event carries no title, no description, no location, and no attendee list, just proof that the time is taken. If you’d rather share more on one side, say, letting your partner’s calendar show real event titles, you can opt in to full details or a custom title, but the starting point is private, not something you have to remember to lock down.

Fits the free tier

This is exactly the use case the Free plan is built for: one connection, between two calendars, kept in sync indefinitely. You don’t need Pro’s 6 connections or Business’s 30 unless you’re also juggling client calendars or managing a team, a single work-personal pair runs entirely on Free.

If your situation grows, you pick up a side project, or a second personal account enters the picture, the same connection model scales with you. You’d just add another connection rather than replace the one you already trust.

Setting it up

1. Connect both accounts. Sign in and authorize your work and personal Google accounts through Google’s own OAuth, no password ever passes through 2calendars, and you can revoke access from Google at any time.

2. Turn on two-way sync. Set the connection to mirror in both directions, so a booking on either calendar blocks the other automatically.

3. Confirm Busy-only is selected. It’s the default, and it’s the right choice for a work-facing connection, leave it as is unless you specifically want to share more.

4. Test it. Create a placeholder event on one calendar and confirm it shows up as “Busy” on the other within seconds. Edit or delete it and watch the mirror follow along.

Once it’s running, 2calendars’ health monitoring keeps an eye on the connection for you, if a Google permission gets revoked or something else breaks the link, you’ll be notified instead of finding out the hard way.
