Tokyo is 15h ahead of Calgary on this date
Every hour in Calgary and the corresponding time in Tokyo. Green rows indicate business hours in Tokyo.
Time zones
Calgary uses America/Edmonton (MDT) and Tokyo uses Asia/Tokyo (GMT+9). The difference can shift during daylight saving changes, so checking the exact date matters.
Best use
Use the green rows to spot normal working hours in Tokyo. For teams across more cities, open the meeting planner and compare up to five locations.
Plan a meetingMeeting guidance
There is no full business-hour overlap in the 24-hour table, so use a custom time or rotate meeting times for fairness. For important calls, check the meeting date because the offset can change when either location enters or leaves daylight saving time.
