Lighting LEDs by time schedule

I don't see anything in the serial output that confirms that the LEDs are turning on. That's correct.

I have not modified the header file, I can do that and see if that helps.

The (alarmrepeat) cannot provide provide me the separation of a different schedule on Saturday and Sunday from the rest of the week. Perhaps if there is a way to do that I can abandon the source I got my library from and go with the standard library, but I'm not sure how to do that.

I may be using a different library from that one, although I can't seem to remember where I got it from. The readme from the one I am using contains:

Alarms can be specified to trigger a task repeatedly at a particular day of week and time of day:
Alarm.alarmRepeat(dowMonday, 9,15,0, MondayMorningAlarm);
This would call the function WeeklyAlarm() at 9:15am every Monday.

If you want the alarm to trigger once only on a particular day and time you can do this:
Alarm.alarmOnce(dowMonday, 9,15,0, MondayMorningAlarm);
This would call the function MondayMorning() Alarm on the next Monday at 9:15am.
