Work calendar as private blockers

Your work meetings appear as “Busy (work)” in a calendar your family can see. No titles, locations, attendees or descriptions leave the work calendar.

In the app: Add Sync…, the work calendar as the source, the calendar your family sees as the target, and Busy blocker. The copies are titled “Busy (Work)” after the source calendar.

In the config:

[daemon]
log_level = "info"

[accounts.work]
url = "https://caldav.work.example.com/"
username = "alice"
password = { env = "CAPYCAL_WORK_PASSWORD" }

[accounts.nextcloud]
url = "https://cloud.example.org/remote.php/dav/"
username = "alice"
password = { file = "nextcloud.secret" }

[calendars.work]
account = "work"
url = "https://caldav.work.example.com/calendars/alice/default/"

# An empty calendar on the family Nextcloud, shared with the family
[calendars.work_blockers]
account = "nextcloud"
url = "https://cloud.example.org/remote.php/dav/calendars/alice/work-blockers/"

[syncs.work-to-family]
source = "work"
target = "work_blockers"
interval = "5m"

transforms = [
  { field = "SUMMARY", action = "set_field", value = "Busy ({{source_name}})" },
]

What happens:

• Without fields, only the times, the recurrence rules, the status and the free/busy flag are copied. SUMMARY is not copied; the set_field transform adds a new one.
• Events you marked as “free” stay free, so they don’t block the family calendar. Cancelled meetings are not copied.
• Recurring meetings stay a single series in the target.
• nextcloud.secret is read from the config’s directory.

If the work calendar is in Calendar.app (Exchange, Google), use Calendar.app to Nextcloud instead.

Variations:

• Add fields = ["LOCATION"] to see where a meeting takes place.
• Add { action = "skip", when = [{ all_day = true }] } (in the app Skip events with Event set to is all-day) if all-day events (holidays, out-of-office) shouldn’t block a whole day; see skip.
