Frequently Asked Questions
When is the full moon in 2026?
Full moon dates 2026 (approximate): 13 Jan, 12 Feb, 13 Mar, 12 Apr, 12 May, 11 Jun, 10 Jul, 9 Aug, 7 Sep, 7 Oct, 5 Nov, 4 Dec.
What is a supermoon?
A supermoon occurs when a full moon coincides with perigee (closest approach to Earth). The moon appears up to 14 % larger and 30 % brighter than a minimoon (full moon at apogee).
Does the moon really influence plant growth?
Biodynamic farming (after Rudolf Steiner) follows moon calendars. Scientific evidence is inconclusive. Practitioners report better results planting during waxing and harvesting during waning moon, but controlled studies are lacking.
What is the difference between new moon and full moon?
New moon: the moon is between Earth and Sun – the facing side is unlit, the moon is invisible. Full moon: Earth is between moon and Sun – fully illuminated. Approximately 14.75 days pass between new and full moon.
What is the Moon Calendar?
The moon calendar shows current moon phases, dates of the next new moon and full moon, as well as moonrise and moonset for every day of the year.
How does the Moon Calendar work?
Based on astronomical calculations (synodic period: 29.53 days) the calculator determines the moon phase for any date. Shown: phase (new moon, waxing, full moon, waning), illumination percentage and calendar position.
Key Data and Facts
Synodic period: 29.53 days (new moon to new moon). Moon phases: New (0 %), Waxing Crescent, First Quarter (50 %), Waxing Gibbous, Full (100 %), Waning Gibbous, Last Quarter (50 %), Waning Crescent. Supermoon: full moon at perigee, appears ~14 % larger. Blue moon: 2nd full moon in calendar month.
Step-by-Step Guide
Understanding moon phases: 1. New moon: moon between Earth and Sun – invisible. 2. Waxing crescent: crescent grows from right (N. hemisphere). 3. First quarter: right half illuminated. 4. Full moon: entire visible side lit. 5. Waning: crescent shrinks from left. 6. Gardening: traditionally plant during waxing, harvest/prune during waning moon.
Calculation Example
Full moon May 2026: 12 May. New moon June 2026: 25 June. Moon phase today (11 May 2026): waxing gibbous, approx. 90 % illumination.
