Technically
Monday 23:30 - Wednesday 00:30 would be 3 Calendar days,
but I highly doubt that that would be what TC is talking about.
CARs 700.19 (1) Subject to subsection (2), an air operator shall provide each flight crew member with the following time free from duty:
(a) where the operation is conducted under Subpart 4 or 5 using an aircraft other than a helicopter, one period of at least 36 consecutive hours within each 7 consecutive days or one period of at least 3 consecutive calendar days within each 17 consecutive days;
(b) where the operation is conducted under Subpart 2 or 3 or is conducted using a helicopter, one period of at least 24 consecutive hours 13 times within each 90 consecutive days and 3 times within each 30 consecutive days; and
(c) where the flight crew member is a flight crew member on call, one period of at least 36 consecutive hours within each 7 consecutive days OR one period of at least 3 consecutive calendar days within each 17 consecutive days.
