Handling Day of Week and Week Number Clicks

ESM migration: keep the existing options and callbacks, import weeks from vanilla-calendar-pro, and add it to the constructor’s extensions: [weeks] array without calling it.

Day of the Week

You can intercept a click on a day of the week and, for example, select all days of the month that correspond to that day of the week.

Week Number

You can display week numbers in the calendar using the enableWeekNumbers parameter and handle clicks on them. Having information about the dates in the selected week, you can easily select these dates in the same way.
