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 immediately beside the time 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 sakura-themed popup to turn durations on or off and switch styles. Your preferences save automatically and update open Calendar tabs. The popup includes gently animated, dithered cherry blossoms and respects your system's reduced-motion preference. Designed to stay out of your way: • Duration text uses black or white for contrast. • Labels stay beside the original time and are omitted when they cannot fit. • 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. All-day events, overnight/multi-day ranges, ambiguous times, unsupported locales, and events showing only a start time are skipped. Google Calendar interface changes may require extension updates.
