Question - How do I add a training day or holiday to the registers?
Answer - Go to Admin > Config > Core Setup > Holidays
At the bottom of the screen click on the Holiday dropdown, select the holiday type, then enter the date of the training or holiday and click add holiday.
Please note the end date of the holiday should be the last day of the holiday not the day the students return to school. For example for a single training day you would enter the same date in the start and end date fields.
