What the eight Moon phases mean
Old almanac lore, not science. The last column is the next time each phase shows at noon in your time zone.
| Phase | What you see | Almanac lore | Next |
|---|---|---|---|
| New Moon | The Moon is dark and almost invisible. | Old almanac lore treats it as a time to rest, plan and start something quietly. | Nov 7 – Nov 10 |
| Waxing Crescent | A thin sliver lit on the right (northern hemisphere), growing each night. | Lore calls it a time to set intentions and begin building. | Nov 11 – Nov 14 |
| First Quarter | Half the disc is lit; the Moon is high at sunset. | Lore calls it a time to act, decide and push through obstacles. | Nov 15 – Nov 18 |
| Waxing Gibbous | More than half is lit and still growing. | Lore calls it a time to refine, adjust and get ready for the peak. | Nov 19 – Nov 22 |
| Full Moon | The whole disc is lit and rises around sunset. | Lore calls it a time of peak, completion and celebration. | Oct 27 |
| Waning Gibbous | More than half is lit, but shrinking each night. | Lore calls it a time to share, give thanks and pass things on. | Oct 28 – Oct 30 |
| Last Quarter | Half the disc is lit again, on the opposite side from the first quarter. | Lore calls it a time to let go, review and clear away what no longer works. | Oct 31 – Nov 2 |
| Waning Crescent | A thin sliver before dawn, fading toward the next New Moon. | Lore calls it a time to rest, finish up and prepare for a new cycle. | Nov 3 – Nov 6 |
Questions
Scroll the list to see which upcoming days Moon lore favors for starting a diet, each with its reason, and add any day to your phone calendar. Pick a day that fits your own schedule and health plans, since the Moon is only one traditional guide.
Which days in the next 60 are best to begin a diet?
By traditional Moon-sign and phase lore, 32 days from Tue, Oct 27 to Fri, Dec 25 rate good or better. The nearest is Wed, Oct 28; the top pick is Wed, Oct 28.
How are Moon days worked out?
We take the Moon’s sign and phase at local noon in America/New York. If the Moon changes sign within two minutes of noon, the day is rated on the less favorable side.
Is this science?
No. It follows old almanac lore about the Moon. The Moon positions are real astronomy; the meaning given to them is tradition.
Which Moon phase is best for starting a diet?
In Moon lore, the waning Moon is the phase for starting a weight-loss diet. Tradition starts a diet while the Moon shrinks, linking that phase with cutting back. The best days on this site are all waning-Moon days.
Which Moon signs are good for starting a diet?
Moon lore names six best signs: Aries, Gemini, Leo, Virgo, Sagittarius and Aquarius. Lore describes them as barren signs, which it uses for cutting back. No other signs are rated as merely good, and none are listed as ruling a day out for this activity.
What is the best day to start a diet by the Moon?
The best day is one where a waning Moon sits in one of the six best signs. Both conditions are checked together for every day shown. Each day on the list comes with its reason, so you can see which sign and phase it rests on.
Does the day of the week matter for starting a diet in Moon lore?
No, Moon lore looks at the Moon's sign and phase, not the weekday. A Monday and a Saturday are treated the same if the Moon is in the same sign and phase. Choosing a weekday that suits your routine is up to you.
Should I wait for a lucky day to begin a diet?
That is your call, since this is tradition and not a rule. Many people use the list as a gentle nudge to pick a start date. For any diet or health change, follow advice from your own doctor or dietitian.
