This will be Fri/Sat night 6PM to 11PM PACIFIC STANDARD ie. California time, please convert appropriately if you're Australian.
tl;dr for Melbourne it'd be either 11AM to 4PM, 12PM to 5PM or 1PM to 6PM depending on Daylight Savings in both America and Australia. (Both have DST, 1PM to 6PM, only one has DST, 12PM to 5PM, neither have DST, 11AM to 4PM)
