I started December with this old buddy - i still like its charm and technically it is brilliant anyway: L.U.C Lunar One 1st gen, perpetual calendar, all indications jumping instantaneously, orbital moonphase
…but to be honest not in short months. Every day exactly at midnight, big date and day jump. Moonphase switches around 11 am. From Nov 30th Nov to Dec 1st for example, the big date starts to change to 31 around 9pm and then jumps to 1 at midnight…
