About Solunak

What Solunak is

Solunak is an independent moon phase calendar published in Spanish, French, Portuguese and English. The site is a small reference utility focused on a single thing: showing when the four major moon phases happen, in a form that is easy to read in your local calendar.

Solunak has no user accounts, no comments, no forms and no paid features. It is a public reading site supported by display advertising.

What the calendars show

Each calendar page presents the four major moon phase events:

• New Moon — the start of the lunar cycle, when the Moon is between the Sun and the Earth.
• First Quarter — half of the visible disc is illuminated, midway from New to Full.
• Full Moon — the entire visible disc is illuminated.
• Last Quarter — half of the visible disc is illuminated, midway from Full back to New.

Solunak presents these events in three views:

• Landing — the current moon phase and the next major phases for the active language.
• Monthly calendar — all phases occurring in a given month, with local dates and reference times.
• Yearly calendar — an overview of the whole year, with key facts such as the number of Full Moons and any month with two Full Moons (a Blue Moon month).

How dates and times are calculated

A moon phase is a single global event — for example, a Full Moon happens at one specific moment in time worldwide. Calendars, however, are read locally. Solunak handles this in a simple, deterministic way:

• Each phase event is stored as a UTC moment (an exact astronomical instant).
• For every page, the UTC moment is converted to the timezone associated with the locale and reference city of that page (for example, Madrid for Spanish or Paris for French).
• The local date and time shown on the page are derived from that stored UTC source and displayed in the reference timezone of the page.

This means a Full Moon may appear on different local calendar days in different locales — that is the expected behaviour, not a discrepancy. Solunak chooses one reference city per language so that each calendar reads consistently for that audience; the underlying astronomical event is the same everywhere.

Solunak shows the four major phases as point-in-time events. It does not interpolate intermediate phase shapes, daily illumination percentages or daily moonrise and moonset tables on the public calendar.

What Solunak does not do

To keep the project focused and trustworthy, Solunak deliberately stays out of several areas:

• No astrology, horoscopes or zodiac interpretation.
• No medical, beauty, hair or wellness advice tied to lunar phases.
• No gardening, planting or biodynamic recommendations.
• No predictions, forecasts or claims about the influence of the Moon on human behaviour, health or events.

If you are looking for any of the above, Solunak is not the right resource. The site reports lunar dates and times and stops there.

Languages and scope

The calendars are published in four languages: Spanish (/es/), French (/fr/), Portuguese (/pt/) and English (/en/). The Portuguese version is intended to serve both Brazilian and Portuguese readers; the English version is a global English locale rather than a country-specific edition.

The calendars cover the current year and the next two years. Older English yearly pages remain available as historical reference for readers arriving from an earlier site.

Who publishes Solunak

Solunak is published independently under the Solunak brand. It is run as a small, single-purpose project, not on behalf of a company or organisation. The publisher acts as data controller for the limited personal data described in the privacy policy.
