How to set the time in the perpetual calendar? Yes, how did it change when I quit?

Generally, a digital calendar adjuster has four keys, namely, exit, run (down), up and set, corresponding to D, C, B and A respectively.

First press the "Set" button (enter the time setting state, the year flashes), and you can press the "Up" or "Down" button to modify the year.

2. After modification, press the "Set" key to move the flicker to the Gregorian calendar "Month", and press the "Up" or "Down" key to modify the month; Day, hour, minute and second can be set in the same way;

Week, lunar month and day will change automatically with the change of Gregorian calendar.

Third, press the "Set" or "Exit" key to exit the time setting and return to the normal time state.

I hope my answer can bring you some help.
