Llewellyn's 2026 Moon Sign Datebook: Weekly Planning by the Cycles of the Moon (Llewellyn's 2026 Calendars, Almanacs & Datebooks, 10) by Michelle Perrin

Weekly spreads keyed to the lunar cycle. Every week gives the Moon's sign and phase alongside the space to actually plan, so lunar timing is part of the page rather than something you look up elsewhere.

Mercury retrograde periods marked throughout. Flagged in the weekly layout, so you see them coming instead of discovering them after the fact.

Planting and fishing days. The almanac tradition Llewellyn has published since the nineteenth century, carried forward: best days for sowing, harvesting, and going out on the water.

Lay-flat spiral binding. The book stays open where you put it, which is the whole argument for a spiral planner over a bound one.

Beyond the weekly grid, the datebook carries a run of lunar essays and illustrations that give the year some texture: the second-century account that stands as the first fiction ever written about a voyage to the Moon, the phenomenon of earthshine that Leonardo da Vinci correctly explained centuries before anyone confirmed it, samples returned from the far side, the practical arithmetic of lunar tourism, and the mechanics behind Black Moons and Supermoons.

Each month opens with an at-a-glance page: New and Full Moons, plus the specific gardening dates for that stretch of the year.

Working by the Moon is one of the oldest organizing habits humans have. The lunar month is legible without instruments, it repeats reliably, and every agricultural society on record built some version of a planting calendar around it. What a datebook like this does is put that inheritance back into contact with an ordinary working week.

In contemporary practice the waxing Moon is worked for drawing and building, the Full Moon for culmination and charging, the waning Moon for release and banishing, and the Dark Moon for rest and divination. A planner that shows you the phase on the same line as your appointments makes that correspondence usable rather than theoretical. You stop asking what phase it is and start noticing what you scheduled during it.

1. Read the week before you fill it. Check the Moon's sign and phase for the coming seven days before you commit to anything you have discretion over.
2. Front-load the waxing weeks. Launches, pitches, first meetings, and anything you want to grow traditionally go into the building half of the cycle.
3. Save the waning weeks for clearing. Endings, cancellations, cleaning out, and closing accounts sit naturally in the releasing half.
4. Note the retrogrades and plan around them, not in fear of them. Mercury retrograde is a period for reviewing and revising, not a curse. Use the marked spans to schedule the second look rather than the first launch.
5. Use the planting dates if you garden. The best-days tables are the almanac's oldest feature and they are genuinely usable in a working garden.

• Llewellyn's 2026 Daily Planetary Guide. The Datebook gives you the Moon; the Planetary Guide gives you every other body. Astrologers who want full transits alongside their week keep both open.
• Llewellyn's 2026 Magical Moon Calendar. The wall companion to the desk book, for households where the whole family should be able to see the phase without opening anything.
• Llewellyn's 2026 Witches' Datebook. The sister planner, organized around the Wheel of the Year and sabbat practice rather than lunar timing.
• Llewellyn's Little Book of Moon Spells by Melanie Marquis. Once the datebook has told you what phase you are in, this tells you what to do with it.
• Moon Phase Embossed Leather Journal with Latch. The place for the reflection the planner has no room for; keep them side by side.

Llewellyn Publications has been printing almanacs since 1901, which makes its Moon Sign line one of the longest continuously published astrological series in the United States. The best-days tables in this datebook descend directly from that lineage, and from the older American farmer's almanac tradition it grew out of. Michelle Perrin, who contributes to this edition, writes astrology under the name Astrology Detective.

What year does it cover? The full calendar year 2026, January through December. It is a dated annual, so it does not carry into 2027.

Do I need to know astrology to use it? No. The Moon's sign and phase are printed for you, and the best-days tables are just dates. You can use it as a lunar planner from day one and learn the astrology at whatever pace suits you.

How is this different from the Moon Sign Book? The Moon Sign Book is a reference almanac with articles and tables. This is a planner you write in. They are designed as companions, and many readers keep both.

Is it really spiral bound? Yes, and it lies flat. That is the point of the format.

Are the forecasts predictions? No, and we would not sell them as such. Astrological timing is a reflective framework for thinking about how you spend a year. Nothing in this book is financial, medical, or legal advice, and no almanac substitutes for a professional when you need one.
