Set calendar default duration to your actual most-common…

When This Fires

• When configuring calendar settings for the first time or reviewing them
• When you notice repeatedly overriding the calendar's default meeting duration
• When implementing Default to 25 or 50-minute meetings instead of 30 or 60…'s 25/50-minute meeting standard
• Complements Default to 25 or 50-minute meetings instead of 30 or 60… (25/50-minute defaults) with the tool-configuration step that makes the standard automatic

Common Failure Mode

Vendor-default acceptance: using 30-minute and 60-minute defaults because "that's what Google Calendar uses." The vendor's default was set for the average user across all use cases; your default should be set for your specific meeting patterns.

The Protocol

(1) Review your last 30 meetings. What duration did you schedule most often? This is your empirical mode. (2) Change your calendar's default meeting duration to this mode. Most calendar apps allow this in settings (Google Calendar: Settings → Event Settings → Default Duration). (3) For the 10% of meetings that need a different duration, override manually. The override is now the exception, not the norm. (4) If you're implementing Default to 25 or 50-minute meetings instead of 30 or 60…'s 25/50-minute standard, set the default to 25 and manually extend to 50 for meetings that need it. (5) Periodically check: has your empirical mode shifted? If you've moved from 25-minute to 15-minute meetings, update the default. The default should track your actual behavior, not your historical behavior.
