All-day events

All-day events are usually reminders, not commitments: birthdays, public holidays, “trade fair week”, “Peter working from home”. If they were transferred as busy, the whole day in the target calendar would be blocked — and nobody could book you although you’re free.

Default: treat as free

That’s why all-day events are transferred as free by default: they appear in the target but don’t block any time. A public-holiday calendar as a source stays completely harmless this way.

Alternative: block the whole day

The setting in the visibility step: “Free” (default) or “Blocked” — with live preview.

If an all-day event really should block (e.g. vacation), you have two options:

1. Per sync: when creating, in the “Visibility” step, expand the “All-day events” card and pick “Blocked” instead of “Free” (default). This then applies to all all-day events of that sync; with a two-way sync it can also be set per direction.
2. Per event: create the vacation as a regular timed event (e.g. 8am–6pm) — that’s always transferred as busy, regardless of the option.

Tip: if only individual all-day events should block, option 2 is usually better — otherwise all birthdays suddenly block too.

Exception: an all-day event marked as out of office in the source (Outlook “Show as: Away”, Google “Out of office”) always blocks, even when “Free” is selected.

Working-location entries (Google)

Google Calendar can show a working location per day, such as “Home” or “Office”. These are not appointments. Whether they appear in the target is set in its own “Working location” card, directly below “All-day events”:

• Leave out: no entry appears in the target calendar.
• Copy: the working location appears in the target as a free entry, such as “Home”, and blocks nothing.

New syncs are set to “Leave out”. Existing syncs are set to “Copy” until you change it. If you switch to “Leave out”, the existing copies disappear from the target calendar. For two-way syncs the setting applies to both directions.

Changing it later

Both options can be changed at any time: in the dashboard via the sharing’s three-dot menu → “Edit” → “Advanced settings”. The existing copies in the target calendar are adjusted automatically → Edit a sharing.
