My mobile phone is Xiaomi 1. Today, my mobile phone calendar shows 1970. What happened and how to get back to today's day.

Enter the desktop, click the time on the desktop, enter the time setting interface, slide to the clock, click the time setting-,and automatically determine the time and date to open.

The open status will automatically update the time.

If the time is still 1970, turn off the automatic determination of time and date, and then click Set Date.
