Planner Notes
Confirm exact new moon instants with a current almanac before publishing. Use this sheet for dark-sky reminders, night photography planning, launch calendars and crescent watch notes.
Assumptions
New moon instants are generated with Astronomy Engine SearchMoonQuarter and quarter 0. The entered UTC offset is applied as a fixed civil-time offset after the UTC search.
Limits
This is a printable planning worksheet, not an official ephemeris, crescent visibility forecast, religious calendar authority, astrological reading or navigation tool. Verify exact phase times before publication.
Method
The worksheet generates new moon dates from the astronomy engine and turns them into practical planning rows
The calculator asks Astronomy Engine for each new moon instant in the chosen year, applies the selected UTC offset, and then derives prep dates, dark-sky windows, weekdays and the season label from the same source-backed date stream.
Lunar basis
New moon instants come from Astronomy Engine SearchMoonQuarter where quarter 0 is new moon, using the same astronomy package as the site instruments.
Print path
The print button opens browser print. The print stylesheet keeps the new moon list, prep dates, dark-sky windows, assumptions, notes and source limits.
Limits
This is a planning calendar, not an observatory almanac, crescent-visibility forecast, religious calendar authority, astrology claim, navigation aid or official lunar phase source.
Source Notes
New moon dates can shift by location when the phase occurs near midnight
CalculationTime uses Astronomy Engine phase searches for printable planning worksheets. Exact new moon instants should still be checked against official almanacs or observatory data before publishing dates, booking travel, planning public events or making scientific claims.
