The calendar above is based on my personal research from Annual Attic Festivals and calculated for US Mountain Standard Time. The festivals technically begin starting the evening of the previous day (since days traditionally began at sunset). To accommodate for local variation, compare your region's sunset to Athens' and adjust accordingly. This chart is fair use so feel free to copy and share, just don't claim it as your own.
