How to realize the function of easy language date box, thank you.

Wednesday, September 13, 20 18, this is not a standard time format.

[20 13 September 18], this is.

Take "week" as the separator, and separate the text "Wednesday, 2065438+September, 2003 18", with the standard time in front and the week in the back. Can be separated

Replace "year" and "month" in "20 13 June 18" with "-"as sub-text, and replace "day" with ""empty text. You can get: 20 13-9- 18.

Take the year (), month () and day () from the time format [20 13 September 18] to get 2013,9, 18, and then assemble it according to your own format.
