Calendar Sync for Small Teams, Clubs, and Churches

A small organisation runs on a shared calendar - practice times, service rosters, committee meetings, the hall booking that mustn't clash with choir. But small organisations almost never standardise on one calendar provider. The treasurer uses Outlook for work, the volunteer coordinator lives in Gmail, and the youth leader is on a personal Microsoft account. Everyone's looking at "the calendar," but it's not the same calendar - and the gaps cause the double-booked hall and the meeting half the committee misses.

The mixed-provider problem small groups always hit

Unlike a company that mandates one stack, a club, church, or community team is a coalition of whatever accounts people already had. That creates a predictable mess:

• The shared schedule gets maintained in one provider, and everyone on the other provider is stuck with a stale, read-only view.
• Someone tries the built-in ICS subscription, but it's one-way and lags by hours - so the Outlook half of the team is always looking at yesterday's plan.
• People resort to screenshots in a group chat or re-typing events by hand, which goes wrong the moment something moves.

The result is two camps with two versions of the truth, and the friction lands on whichever volunteer is least equipped to fix it.

What a small team actually needs

Not a migration project, and not a new platform everyone has to adopt. You need one shared group calendar that's live and editable on both Google and Outlook at once:

• Add "Sunday 10am service" or "Tuesday training" from whichever app an organiser uses, and it appears for the others.
• Move the committee meeting in Google and the Outlook organisers see the new time within about a minute.
• Cancel a fixture and the hold clears everywhere, so the hall doesn't look booked when it isn't.

This is two-way, real-time sync - the opposite of the slow, read-only ICS link - and it's what keeps a volunteer team from drifting into two conflicting calendars.

How Calendar Family solves it

Calendar Family connects a Google account and a Microsoft/Outlook account and keeps a chosen group calendar in two-way sync between them in real time via webhooks. The setup runs once and then stays out of the way:

1. Click Add calendar and choose Google as the provider - for example a Google calendar named "St. Mark's Events" or "Riverside FC." You'll go through Google's standard consent screen; access is revocable at any time, and the calendar then appears under Manage providers.
2. Click Add calendar again and choose Microsoft for the Outlook account - personal and work/school Microsoft accounts both work.
3. Click Add connection and pick the group calendar as the source and a calendar on the other provider as the target.
4. Set a sync direction (Two-way) and choose what to share - All details for a public schedule, or Free/busy only if you only want to show that a slot is taken.
5. Let the first sync reconcile, then organisers just work in their own apps.

Within each provider, you keep sharing the calendar with your organisers exactly as before. Calendar Family's job is bridging the two providers so neither half of the team is left behind.

What's free

The free tier covers real-time two-way sync - enough for a shared group calendar spanning Google and Outlook, which is the core need for most clubs, churches, and small teams. It's a real free tier, not an expiring trial, which suits groups running on volunteer time rather than a budget. Calendar Family is privacy-respecting - no profiling, no data selling - and you control exactly which calendar and how much detail is shared.

One calendar your whole group can trust

Your members shouldn't need the same email provider to read the same schedule. Connect the two accounts, point them at your group calendar, and let everyone keep their own app while finally sharing one plan.
