Ancaster runs on a Day 1 (odd calendar days) and Day 2 (even calendar days) flip schedule. Students should plan ahead and arrive at their classes in a timely fashion. If students are ordering online food deliveries, they must plan for delivery during break or lunch time, not during class.
Here are the bell times:
| Time | Day 1 | Day 2 |
| 8:15 – 9:30 am | PERIOD 1 | PERIOD 2 |
| 9:30 – 9:40 am | Break | Break |
| 9:40 – 10:55 am | PERIOD 2 | PERIOD 1 |
| 10:55 am – 11:55 am | Lunch | Lunch |
| 11:55 – 1:10 pm | PERIOD 3 | PERIOD 4 |
| 1:10 – 1:20 pm | Break | Break |
| 1:20 – 2:35 pm | PERIOD 4 | PERIOD 3 |
