Here is a list of the session times for the 2020 Simon Marais Mathematics Competition, ordered by time-zone. These session times are all given in local time. So the first sessions to take place will be those in New Zealand and (within Australia) ACT, NSW, and Victoria; South Australia will be half an hour later; Queensland will be an hour later; South Korea will be two hours later; and all other locations will be three hours later. As a result, the first session in the latest starting locations will commence exactly when the first session in New Zealand ends, and likewise for the second.
