For everyWeekDay and everyWeekend there is also an option to change the starting day.

By default, week days is from Monday to Friday while weekend days are Saturdays and Sundays

This can be changed like so:

cronTime.everyWeekDay("sunday", "thursday");
// 0 0 * * 0-4
// from Sunday to Thursday

cronTime.everyWeekDayAt(1, 30, "sunday", "thursday");
// 30 1 * * 0-4
// 1:30 AM from Sunday to Thursday

cronTime.everyWeekend("friday", "saturday");
// 0 0 * * 5,6
// on Friday and Saturday

cronTime.everyWeekendAt(1, 30, "friday", "saturday");
// 30 1 * * 5,6
// 1:30 AM on Friday and Saturday

Note: if a startDay is specified then an endDay must be specified also, else it will use the default values which may not tally with your new $startDay

Every method of CronTime returns exactly what its name says.
