Lunar calendar built into your yearly planner
Big Year ships a dedicated MOON tab: a full-year moon phase calendar in Google Sheets. Each day shows the phase with a formula based on the synodic month. No separate moon app, no paid lunar calendar download. Open MOON after you copy Big Year free.

What phase is the moon today?
The MOON tab answers template intent: see every phase for the year, then jump to today in SETTINGS. Big Year will not beat a live moon widget for second-by-second accuracy, but it wins for planners who want a printable lunar calendar tied to the rest of their year.
