Never a fixed exact 29.5 days.
Same technique used in professional ephemerides.
Real sequence chained from the same function the tool uses; the gaps are 29.52 and 29.63 days, showing the month-to-month drift.
It's the Moon's visual shape at that moment (how much of the Sun-lit disc we can see from Earth), classified into one of 8 traditional names (New, Crescent, First Quarter, Gibbous, Full, and so on) based on the angle between the Sun and the Moon in the sky.
Yes, the calculation is done in UTC and then automatically converted to the time zone configured on your device.
No, the lunar month (29.53 days) and the civil month (28 to 31 days) are not synchronized, so the New Moon drifts freely across the civil calendar throughout the year.
Yes, the full calendar below lets you navigate month by month and see each day's phase, not just the next event.
