Moon Phase Calendar

Moon Phase Calendar opens straight to tonight's moon. No setup, no account, no sign-in — the phase, illumination and moon age are on screen the moment you launch.

TONIGHT AT A GLANCE
• Phase name, illumination percentage and moon age in days
• A drawn moon disc that matches the real terminator, not a generic icon
• Days remaining until the next full moon and the next new moon

A FULL MONTH, NOT JUST TODAY
• Every day of the month with its own phase glyph
• Tap any day to see that night's detail
• The next eight principal phases — new, first quarter, full, last quarter — with exact dates

BUILT ON REAL ASTRONOMY
Phases are computed on your device from established astronomical algorithms, not looked up from a table. That means every date works, past and future, with no network and no location permission — moon phase is the same wherever you stand.

WORKS OFFLINE, ASKS FOR NOTHING
• No location access
• No account
• No internet needed for any calculation
