Google Calendar Event Length

Display durations on supported Google Calendar Day and Week event blocks.

See how long your Google Calendar events last without doing the math. Google Calendar Event Length adds a compact duration beside the time, or below it when a tall event is too narrow for an inline label, in supported Day and Week event blocks. For example, 9:11–11:32pm displays “2h 21m.” Choose the style you prefer: • Outlined badges, such as “1h 30m” • Simple parentheses, such as “(1 hr 30 min)” Open the extension's popup to turn durations on or off and switch styles. Your preferences save automatically and update open Calendar tabs. The popup shows a small animated ASCII tear-away calendar and respects your system's reduced-motion preference. Designed to stay out of your way: • Duration text uses black or white for contrast. • Labels appear beside the original time first, fall below it when there is enough room, and are hidden when neither placement fits. • Supported short events can get labels using their accessible time ranges, and supported event details also show durations. • Labels do not intercept event clicks or add keyboard tab stops. • Calendar data is processed locally; event content is not stored or sent anywhere. • No separate account, backend, analytics, or external API is required. Current limits: supports unambiguous same-day time ranges in English AM/PM and 24-hour formats. When a label cannot fit beside or below the time, it is hidden; click a supported event to see its duration in the details popup. All-day events, overnight/multi-day ranges, ambiguous times, and unsupported locales are also skipped. Google Calendar interface changes may require extension updates.
