Calendar Stats — Meeting Volume and Time Audit

Show meeting statistics for a time period.

Arguments

$ARGUMENTS — time range (default: last 30 days):

• "last week", "this month", "last 90 days"
• "2026-01-01 to 2026-03-01" → date range
• Empty → last 30 days

Steps

DB="$HOME/Library/Group Containers/group.com.apple.calendar/Calendar.sqlitedb"

Output Format

Summary: Total events, total hours in meetings, meetings with others vs. solo, all-day events.

By Day of Week: Bar-style ranking — which days are busiest (events + hours).

Top Calendars: Which calendars have the most events.

Busiest Days: Top 5 days with most events.

Compute average meetings per day. Note if meeting load is high (>4 timed meetings/day on average = "heavy").
