The phase now and time since tabulated New Moon, without personal predictions
Looking for today’s lunar day? This page opens at the current UTC minute. The former counter divided a mean cycle into 24-hour blocks: it was not a verified universal lunar-day system. We now show time since a tabulated New Moon instead, without Moon-sign or personal advice claims.

Data range: primary phases 2025–2030; hourly illumination 2026 only.
Phase moments: Fred Espenak, NASA/GSFC, based on Jean Meeus’ Astronomical Algorithms (1998). NASA phase table (UT).
We reproduce the table to its published minute resolution; we do not claim accuracy to a second or a guaranteed one-minute error. In twelve selected 2026 checks against USNO, differences were 0 or 1 minute. This is a comparison of those cases, not an error bound for all dates. UT is represented as UTC for minute-resolution civil display, without a UT1–UTC correction. USNO 2026.
Illumination: the nearest available hourly NASA Scientific Visualization Studio sample for 2026 (DE421 ephemeris), shown with the sample time, not interpolated to your minute. The displayed percentage is rounded to one decimal place; that is display precision, not a measured accuracy. Outside 2026 it is unavailable. NASA SVS 2026.
Example: the table’s New Moon at 2026-10-10 15:50 UT appears as 18:50 in Europe/Moscow and 05:50 on October 11 in Pacific/Kiritimati. The astronomical event is the same; the civil date can differ. ICS stores UTC events with stable identifiers: your calendar chooses its own display zone. The mandatory seconds “00” are format padding; each event is a transparent one-minute marker, not a one-minute physical phase.
This is not a visibility, rise/set, eclipse or personal-advice calculator. The old Moon-sign estimate and mean-cycle lunar-day counter are not used here. No haircut, health, money or legal recommendations are inferred from the data. Dates and zones are not saved by this widget.

This page keeps the familiar today’s lunar day query while separating it from verifiable data. The former counter divided a mean cycle into 24-hour blocks; it was not a verified universal lunar-day system. We now show the phase at the current UTC minute, time since tabulated New Moon and nearby NASA events for 2025–2030. Illumination is available for 2026 only. No haircut, shopping or important-decision advice is inferred from phases.
The page opens at the current UTC minute; Use now refreshes it manually. Choose a display zone to see the same instant in local time. Age since New Moon is elapsed days, not a traditional lunar-day number. For another date, the monthly table and ICS, open the lunar calendar. The source resolution is one minute, not an accuracy guarantee.
This calendar is for checking published Moon-phase events and comparing UTC with a chosen display zone. It does not offer personal forecasts.
Phase data cover 2025–2030; hourly illumination covers 2026 only. Source resolution is not a guaranteed accuracy. No medical, financial or legal conclusions follow from these data.
