Here's the schedule of event cycles:
3:00 AM -- AM Cycle 1
7:00 AM -- AM Cycle 2
11:00 AM -- PM Cycle 1
3:00 PM -- PM Cycle 2
7:00 PM -- PM2 Cycle 1
11:00 PM -- PM2 Cycle 2
All times are Eastern Standard.
Games are simulated during the Cycle 1 time frames. Worlds are simulated in numeric order and the length it takes to process all worlds depends on the # of worlds and what events are taking place in the worlds.
You can monitor the progress of your world via the Commissioner's Note on the World Office page.
