Why the day of the week moves
A date advances by one weekday each year, because 365 days is 52 weeks plus one day. In a leap year it advances by two, which is why the weekday occasionally jumps. Over the six years in the table above you can watch both patterns: the single-step years and the leap-year double step.
This matters more than it sounds if you are planning around a weekend. An event that lands on a Saturday this year may fall midweek in two years' time, which changes everything from travel to time off.
About December 2026 New Moon
The December 2026 new moon falls at 00:53 UTC on December 09, 2026, at 16°56' Sagittarius. The Moon sits between Earth and Sun, so its dark side faces us: no Moon visible for about a day on either side.
A new moon in Sagittarius is the traditional planting moment of the month — the sky's blank page. Anything begun in the days around it shares the sign's flavor, and the intentions you set now come to full light at the Sagittarius full moon six months later.
