About Next Eclipse

How we track the sky — and where the numbers come from

Next Eclipse is a free, tracker-free tool that tells you exactly when and where the next solar and lunar eclipses happen — starting with the total solar eclipse crossing Spain on 12 August 2026. No ads-first clutter, no sign-up, no cookies chasing you around the web: just a precise countdown, clear maps and the context you need to actually understand each event.

Who builds it

Next Eclipse is made by Furiosa Studio, an independent studio that builds small, focused, genuinely useful web tools. It is a sister project of Next Full Moon. We are not affiliated with NASA or any government agency — we present publicly available astronomical data in a clearer, faster form. You can reach us through the Support page.

How we calculate every eclipse

Every eclipse date, time, type (total, annular, partial), magnitude and ground track on this site is derived from NASA's authoritative eclipse catalogs — chiefly the Five Millennium Canon of Solar Eclipses and its lunar counterpart, computed by Fred Espenak and Jean Meeus at NASA's Goddard Space Flight Center. Those catalogs give each event to the second in Terrestrial Time; we convert to Universal Time and then to your local time, applying the standard ΔT correction.

The site is deliberately self-updating. A build runs automatically every day and advances the data: once an eclipse has passed, it moves to the History section and the countdown re-points to the genuinely next event. That is why "the next eclipse" here is always current — never a stale date left over from last year.

Our sources

Accuracy & corrections

Astronomical predictions this far ahead are extremely reliable — eclipse timings are known centuries in advance. Where we add value is in translation: local times, city-by-city circumstances, and plain-language explanations. We cross-check each figure against more than one catalog before publishing. If you ever spot something that looks wrong, please tell us through the Support page and we will correct it.

A word on safety

Watching a solar eclipse safely matters: never look at the partial phases without certified solar filters (regular sunglasses are not enough). We keep a full, free guide on the How to watch page. Lunar eclipses, by contrast, are completely safe to view with the naked eye.


Next Eclipse is free and always will be. If it is useful to you, you can help keep it online from the Support page.
