Tutorial: Blocking Time Across All Calendars in One Click

How time blocking works in manyCalendars

When you have a confirmed meeting on one calendar, your other calendars have no idea that time is taken. Colleagues on those other calendars will happily schedule over it because, from their perspective, you look free. Time blocking solves this by creating a "Busy" hold on your other calendars that matches the duration of your existing commitment.

In manyCalendars, time blocking is a single action. Click on any event, select "Block Time," and choose which calendars should receive the hold. manyCalendars creates a new event on each selected calendar with the title "Busy" and no other details. No meeting description, no attendee list, no hints about what the original event is or which client it belongs to.

What the blocked event looks like

On the receiving calendar, the blocked event appears as a simple "Busy" hold. Other people in that organization see only that you are unavailable during that window. They cannot tell whether you are in another meeting, doing focused work, or at a dentist appointment. The privacy boundary is absolute.

In manyCalendars's unified view, blocked events are visually distinct from source events. They appear with a dashed border and a lighter opacity, so you can tell at a glance which events are real meetings and which are holds you created. This prevents the confusion of looking at your own calendar and wondering "wait, what is this Busy block?"

Why proactive blocking matters

Reactive blocking (waiting until a conflict appears, then fixing it) works, but it creates unnecessary back-and-forth. Someone schedules over your committed time, you decline, they reschedule, you accept. Two people did work that did not need to happen.

Proactive blocking prevents the conflict from occurring in the first place. The moment a meeting is confirmed on Calendar A, you block that time on Calendars B, C, and D. Now anyone checking your availability on those calendars sees you as unavailable. The meeting invite never gets sent. The conflict never materializes. Zero back-and-forth.

The best practice is to block immediately after accepting any meeting. Make it reflexive: accept the invite, click "Block Time," move on. It takes about 5 seconds and prevents scheduling headaches that could take 15 minutes to resolve later.

Setting up recurring blocks

Some commitments are recurring: weekly standups, biweekly sprint reviews, monthly board meetings. For these, you want recurring blocks that match the cadence of the original event.

In manyCalendars, when you block time for a recurring event, you have the option to make the block recurring as well. Select "Block all occurrences" and manyCalendars will create matching holds on your other calendars for every instance of that recurring meeting. If the original recurring event gets rescheduled or canceled, update or remove the corresponding blocks manually.

A good setup routine when onboarding a new client: identify all recurring meetings in the first week, then block each one across your other calendars. This five-minute investment on day one prevents weeks of potential conflicts.

Block time, save time

Time blocking is the simplest form of conflict prevention. It costs seconds per event and saves the much larger cost of managing double-bookings after the fact. The fewer conflicts you have to resolve, the more your calendar works for you instead of against you.

Your other calendars should know what your primary calendar already knows. Install manyCalendars for free and start blocking in one click instead of manually creating holds across three different calendar apps.
