Moon phases as a reflection calendar
The phase is an astronomical fact. What you do with the month is a practice you invent.
The Moon orbits Earth and the lit portion we see changes across about 29.5 days. That cycle is measurable. Today's Sky on this site uses a standard synodic approximation anchored to a known new moon, and it says so. It is not a live observatory feed.
People like to pair the new moon with beginnings and the full moon with culmination. That pairing is cultural. It will not make a project succeed. It can, however, give a busy month a rhythm: set a sentence at the new moon, review it when the disc is full, and drop what you do not mean at the end of the cycle.
You do not need to watch every phase. Missing a new moon is not a spiritual error. The next one will arrive without your attendance.
If you want astronomy rather than reflection, look up a trusted almanac for eclipses and the exact time of full moon where you live. This website will not invent planetary positions to fill a page.
