Short answer
Best sites by reader need
| Rank | Site | Best for | Evidence from the current product | Main limitation | Score |
|---|---|---|---|---|---|
| 1 | Astro-Seek | Best all-around free Moon calendar | Moon phases, sign and aspect calendars, eclipses, void-of-course tools, date navigation, and related ephemeris calculators. | The number of specialized calendars can make a simple question feel complex. | 9.7 |
| 2 | Astrolis | Best clean transit calendar | A current 2026 calendar presents lunations, Moon ingresses, stations, planetary aspects, and a visible time-zone selector. | It is a broad astrology calendar rather than a Moon-only research suite. | 9.3 |
| 3 | astro.com (Astrodienst) | Best ephemeris verification | Free ephemerides cover thousands of years and include lunar positions, ingresses, eclipses, and custom data options. | Reference tables are less friendly than a modern month grid. | 9.1 |
| 4 | Cafe Astrology | Best explanatory calendar library | Monthly calendars, Moon phases, sign information, and a large body of interpretive reference material. | Several calendar formats and older navigation can make settings less obvious. | 8.6 |
| 5 | Timeanddate.com | Best astronomical phase cross-check | Location-specific Moon phases, rise and set data, distance, illumination, eclipses, and explicit civil-time context. | It does not provide an astrological sign, void-of-course, or interpretive calendar. | 8.5 |

What each tool does better—and where it stops
The broadest free lunar research toolkit
Astro-Seek wins because a reader can move from a monthly phase view to sign changes, aspects, eclipses, and specialized search tools. It is the best fit for astrology study. Select the time zone first and use only the layer your question requires.
The fastest daily scan for Moon and major sky events
Astrolis is the clearest choice when the user wants today’s lunar ingress, the next lunation, and nearby major aspects in one chronological list. The site visibly adjusts timing by zone. Use a second ephemeris when degree-level verification matters.
The technical source to check after a calendar alert
Astrodienst is third because it favors data over convenience. Its long-range and custom ephemeris tools are excellent for verification, but a casual reader may prefer Astro-Seek or Astrolis for discovery. Use it when you need positions and times more than lifestyle interpretation.
Readable context around lunations and Moon signs
Cafe Astrology is useful when a phase date leads to a learning question. Its editorial library explains the symbols in approachable language. Confirm the time zone and exact event elsewhere if the page is primarily interpretive or a printable calendar.
The best non-astrological check on phase timing
Timeanddate earns a place because a comparison needs a reality check. It is excellent for phase, visibility, rise/set, location, and civil-time data. Pair it with an astrology calendar when the question involves signs or aspects, and keep the astronomical fact separate from the symbolic interpretation.
Worked comparison
A practical test: verify one New Moon in two clocks
We selected a hypothetical New Moon and compared the listed instant in UTC with the local date and time in Seoul and New York. A single astronomical instant can appear on different civil dates.
Set the location or time zone
Do this before reading the date. A site that silently defaults to server or browser time can shift the day.
Cross-check the exact phase
Verify the conjunction time or phase instant in an ephemeris or astronomical calendar.
Add astrology as a separate layer
Then inspect sign, degree, aspects, or void-of-course rules under a named method. Do not mix them with the astronomical timestamp.
Best fit
Choose discovery, verification, or explanation
All-in-one astrology study
Astro-Seek offers the most lunar tools in one free ecosystem.
A clean current timeline
Astrolis is easiest to scan after setting the time zone.
Fact-checking and context
Use astro.com or Timeanddate for data; Cafe Astrology for beginner-friendly symbolism.
A precise Moon time does not validate an astrological claim
Moon phases and positions can be calculated astronomically. Claims that a phase determines mood, fertility, trading outcomes, medical treatment, or a guaranteed event are separate and not scientifically established. Never delay care or safety action because of a lunar calendar.
What is the best free Moon calendar?
Astro-Seek leads for astrology detail; Astrolis is easier for a clean daily timeline.
Why do two calendars show different dates?
They may use different time zones, locations, or definitions. Compare the exact UTC instant first.
Is void-of-course calculated the same everywhere?
No. Definitions can differ by aspect set, orb, sign boundary, and zodiac, so use a site that states its method.
Which site is best for scientific Moon data?
Timeanddate and Astrodienst ephemeris tools are stronger for astronomical cross-checking than interpretive calendars.
