Half the year is that time for me as an american I recommend going to bed early-ish and waking up 30 before the race so you can catch Brundle’s grid walk
Living in Asia, European races are typically 9pm starts, North/South American races are Monday morning around 4am.
I typically have a nap before any race that starts after 9pm, otherwise I will fall asleep as my work means a 4:30am alarm due to starting just after 6.
