Although the majority of big lottery draws take place in the evening between 8 pm and 11 pm, the days of the week that they occur varies for each lottery.
For example, US Powerball and Canada Lotto 6/49 draws happen every Wednesday and Saturday night. Meanwhile, Mega Millions and EuroMillions draws occur every Tuesday and Friday night.
All EuroMillions draws occur on Tuesday and Friday evenings, while Eurojackpot draws take place on Friday evenings.
Therefore, to stay abreast of the next upcoming draw you’re interested in participating in, it’s always best to check the lottery’s official website.
