The correct date has no shorthand format.

The writing of dates should be standardized, indicating the time of year, month and day. The standard format of lunar calendar dates is: the 19th day of the twelfth month of Dinghai year. The standard format of Gregorian calendar date is: February 6, 27; Or February 6, 27. 4/2 or 2/4 is a wrong way of writing, which should be corrected.

At the same time, it should be noted that the date should not be written with decimal point or pause instead of year, month, day and year, and the year number must be written in full, and cannot be abbreviated as February 6, 27 or 7-2-6.
