The format of diary is
Mar 18, 2019
This is my diary
I want to append day of the week to it.
the color of Monday does not fit to the date,
Upon checking the documentation, there is no such a weekday format
The file’s entries are lines beginning with any of the forms specified by the variable ‘diary-date-forms’, which by default uses the forms of ‘diary-american-date-forms’: MONTH/DAY MONTH/DAY/YEAR MONTHNAME DAY MONTHNAME DAY, YEAR DAYNAME
Is it possible to get the weekday inserted?
