The work calendar you can see but can’t share
4-minute read
A subscribed work calendar sits on your Mac and your phone, perfectly visible, and refuses to do any of the three things you want from it: you can’t reshare it, you can’t add to it, and you can’t change how it looks.
This is the most ordinary calendar problem there is. Your employer publishes your schedule as a feed — a subscription URL, a Google account you sign into but don’t own, an Exchange mailbox managed by someone else. The Calendar app shows it. And then every reasonable next step is blocked, because a subscribed calendar is read-only by definition.
So your partner can’t see when you’re travelling. The family shared calendar can’t include your Thursday. You can’t put “leave 40 minutes early, traffic” next to the 4pm. You can’t even give it a colour that stands out, because the feed decides.
The fixes people try first, and why they don’t hold
- Forwarding the subscription URL. It hands over everything — every title, every location, every note, forever, to anyone the link reaches. Many employers rotate or revoke those URLs, and some consider sharing one a policy breach.
- Copying events over by hand. Works for a week. Then a meeting moves, and now you have two schedules that disagree, and the wrong one is the one your household trusts.
- Screenshotting Monday to your partner every Monday. Be honest about how long this lasted.
What Calendar Mirror does instead
It keeps a one-way copy of the locked calendar inside a calendar you own. The copy is an ordinary calendar in your own iCloud account — so it can be shared, coloured, written into, and seen on every device you own. The original is never written to, and nothing is uploaded anywhere: both calendars are already on your device, and the copy is made there.
The setup
- In the Calendar app, make a new calendar in your iCloud account. Call it something like Work (copy).
- In Calendar Mirror, add a pair: source is the subscribed work calendar, destination is the new one.
- Choose how much crosses over. Copy details carries the real title and location and leaves the notes behind — the right default for a calendar other people will see.
- Turn on the filters for declined and canceled events, so meetings you said no to don’t show up as solid blocks in your week.
- Back in the Calendar app, share the new calendar with whoever needs it.
From then on the copy follows the original. On a Mac it reacts to a change within moments, with a five-minute pass underneath to catch anything a notification missed; on iPhone and iPad it refreshes in the background when iOS allows, and a pull-down refreshes it now. How quickly the copy then reaches your other devices is iCloud’s business, not the app’s.
What you get that the feed wouldn’t give you
- A calendar you can share with a partner, an assistant, or a second household.
- Your own colour, your own alerts, your own place in the sidebar.
- Room to add things beside the copies — travel time, a reminder to eat — which the app leaves alone. It only ever touches its own copies.
- A copy that reaches every device on your iCloud account without subscribing each of them to anything.
What this doesn’t fix
Attendees never come across. Apple’s calendar framework gives no way to set participants on an event you create, so a copy carries the time, the title and whatever else you allow, but never the guest list. The copy is one direction only: edits you make to a copy are not sent back to your employer’s calendar, which is usually the entire point, but worth saying out loud. And if your source is a feed you subscribe to, tags in event notes won’t work on it — you can’t edit a feed’s events — so use the filters instead.
