Hi,
I’m not sure you can set day names to one character like “M”, but you can change the format of day names for example to “Mo” for “Monday”, but there are many other possibilities.
With columnHeaderFormat
you can set the day name in the monthview and with the combination listDayAltFormat
and listDayFormat
you can set the day names in the weeklist:
{
"columnHeaderFormat": "dd",
"listDayAltFormat": false,
"listDayFormat": "dd"
}
If you use the shortcode:
[pgc column_header_format="dd" list_day_alt_format="false" list_day_format="dd"]
See for all formats you can use: https://momentjs.com/docs/#/displaying/format/
