macOS Calendar

Manage Apple Calendar events via

$SKILL_DIR/scripts/calendar.sh

. All date handling uses relative math (

current date + N * days

) to avoid locale issues (FR/EN/DE date formats).

Quick start

List calendars

Always list calendars first to find the correct calendar name:

bash

"$SKILL_DIR/scripts/calendar.sh" list-calendars

Create an event

bash

echo '<json>' | "$SKILL_DIR/scripts/calendar.sh" create-event

JSON fields:

Field	Required	Default	Description
`summary`	yes	-	Event title
`calendar`	no	first calendar	Calendar name (from list-calendars)
`description`	no	""	Event notes
`offset_days`	no	0	Days from today (0=today, 1=tomorrow, 7=next week)
`iso_date`	no	-	Absolute date `YYYY-MM-DD` (overrides offset_days)
`hour`	no	9	Start hour (0-23)
`minute`	no	0	Start minute (0-59)
`duration_minutes`	no	30	Duration
`alarm_minutes`	no	0	Alert N minutes before (0=no alarm)
`all_day`	no	false	All-day event
`recurrence`	no	-	iCal RRULE string. See references/recurrence.md

Interpreting natural language

Map user requests to JSON fields:

User says	JSON
"tomorrow at 2pm"	`offset_days: 1, hour: 14`
"in 3 days"	`offset_days: 3`
"next Monday at 10am"	Calculate offset_days from today to next Monday, `hour: 10`
"February 25 at 3:30pm"	`iso_date: "2026-02-25", hour: 15, minute: 30`
"every weekday at 9am"	`hour: 9, recurrence: "FREQ=WEEKLY;BYDAY=MO,TU,WE,TH,FR"`
"remind me 1 hour before"	`alarm_minutes: 60`
"all day event on March 1"	`iso_date: "2026-03-01", all_day: true`

For "next Monday", "next Friday" etc: compute the day offset using the current date. Use

date

command if needed:

bash

# Days until next Monday (1=Monday)
target=1; today=$(date +%u); echo $(( (target - today + 7) % 7 ))

Example prompts

These are real user prompts and the commands you should run:

"Remind me to call the dentist in 2 days"

bash

"$SKILL_DIR/scripts/calendar.sh" list-calendars

Then:

bash

echo '{"calendar":"Personnel","summary":"Call dentist","offset_days":2,"hour":9,"duration_minutes":15,"alarm_minutes":30}' | "$SKILL_DIR/scripts/calendar.sh" create-event

"Schedule a team sync every Tuesday at 2pm with a 10-min reminder"

bash

echo '{"calendar":"Work","summary":"Team sync","hour":14,"duration_minutes":60,"recurrence":"FREQ=WEEKLY;BYDAY=TU","alarm_minutes":10}' | "$SKILL_DIR/scripts/calendar.sh" create-event

"Block July 15 as a vacation day"

bash

echo '{"calendar":"Personnel","summary":"Vacances","iso_date":"2026-07-15","all_day":true}' | "$SKILL_DIR/scripts/calendar.sh" create-event

"I have a doctor appointment next Thursday at 3:30pm, remind me 1 hour before"

bash

# First compute offset_days to next Thursday (4=Thursday)
target=4; today=$(date +%u); offset=$(( (target - today + 7) % 7 )); [ "$offset" -eq 0 ] && offset=7

Then:

bash

echo "{\"calendar\":\"Personnel\",\"summary\":\"Doctor appointment\",\"offset_days\":$offset,\"hour\":15,\"minute\":30,\"duration_minutes\":60,\"alarm_minutes\":60}" | "$SKILL_DIR/scripts/calendar.sh" create-event

"Set up a daily standup at 9am on weekdays for the next 4 weeks"

bash

echo '{"calendar":"Work","summary":"Daily standup","hour":9,"duration_minutes":15,"recurrence":"FREQ=WEEKLY;BYDAY=MO,TU,WE,TH,FR;COUNT=20"}' | "$SKILL_DIR/scripts/calendar.sh" create-event

"Add a biweekly 1-on-1 with my manager on Fridays at 11am"

bash

echo '{"calendar":"Work","summary":"1-on-1 Manager","hour":11,"duration_minutes":30,"recurrence":"FREQ=WEEKLY;INTERVAL=2;BYDAY=FR","alarm_minutes":5}' | "$SKILL_DIR/scripts/calendar.sh" create-event

Critical rules

Always list calendars first if the user hasn't specified one — calendars marked
```
[read-only]
```
cannot be used for event creation
Never use hardcoded date strings in AppleScript — always use
```
offset_days
```
or
```
iso_date
```
Confirm the calendar name with the user if multiple personal calendars exist
Never target a
[read-only]
calendar — the script will reject it with an error
For recurring events, consult references/recurrence.md for RRULE syntax
Pass JSON via stdin — never as a CLI argument (avoids leaking data in process list)
All fields are validated by the script (type coercion, range checks, format validation) — invalid input is rejected with an error message
All actions are logged to
```
logs/calendar.log
```
with timestamp, command, calendar, and summary
