Data notes

What this page calculates

Moon phase angle, illuminated fraction, and quarter events are calculated with astronomy-engine. World times use IANA timezone identifiers through the browser Intl API, so current daylight-saving rules are applied without storing fixed UTC offsets. The reflective prompts are editorial guidance, not scientific or medical advice.

Good to know

How is the moon phase calculated?

We calculate the Moon–Sun phase angle and illuminated fraction from astronomical positions with astronomy-engine. Quarter dates are event calculations, not manually entered calendar dates.

Will the clock handle daylight saving time?

Yes. Each place is identified by an IANA timezone such as Europe/London, rather than a fixed UTC offset. Your browser applies the relevant daylight-saving rule for the displayed date.
