Day-Night Cycle

Morning	4:00am to 9:59am
Day	10:00am to 7:59pm

Daily and Weekly Events

There are some daily and weekly events that you can access by changing the date and time on your Switch. However, most events will not progress until time is resumed in the game since these events usually require you to wait for a certain number of hours.

Events that Do Not Progress	Events that Do Progress
Berry Growth Honey Trees Massage Girl in Veilstone City Ribbons from Julia in Sunyshore Free Belts in Route 221 Daily Lottery Number Trophy Garden Pokemon Solaceon Town News Press	Drifloon in Valley Windworks Sunyshore Market Stickers

Daily and Weekly Events Guide

Time Travelling Penalty

Fair warning, when you choose to time travel, all the events listed above that do not progress will also be paused for about 24 hours.

As an example, if you adjust your system clock, all planted berries will not grow, you won't be able to draw from the Lottery, and you will not have Honey Tree Pokemon spawn for the next 24 hours.

If you really want that Drifloon, it may be better to trade for one.
