How these times are made
- Our server calculates every phase time and sends the finished page. Your browser only keeps the time left up to date, using this device’s clock and counting down to the times already on this page; it asks for nothing after the page loads. If your device’s clock is wrong, the time left will be too; the dates and times shown come from our server.
- Phase times use Jean Meeus’s method (Astronomical Algorithms, chapter 49), rounded to the nearest minute. An automated check compares six 2026 phase times with the U.S. Naval Observatory’s published times and requires agreement within two minutes, so the time left is shown in minutes, never seconds.
- Each phase is one instant, the same everywhere; only the local date and time differ. Local times follow our server’s time-zone rules, which can be out of date where a government changed its clocks recently. For Winnipeg, Casablanca, Vancouver and Edmonton, the page checks every time it shows and warns when one may be an hour off.
- The city you choose is part of the page address, so our server receives it; that is how it writes each time in that city’s time. This site never asks for your location and keeps nothing on your device.
- This page counts down to the Moon’s four principal phases only. It does not count down to a date or time you type.
