Grow a Garden 2 Event Timers

Sam's seed shop rerolls its stock — rarer seeds appear at low odds.

The day runs on a 10-minute loop: 7½ minutes of daylight, a 30-second sunset, then 2 minutes of night — and stealing is only switched on at night. Stay in your own garden to lock it, or go take someone else's crops while they are out.

Every 10 minutes. Wiki: "These refresh every 10 minutes." — https://growagarden2.fandom.com/wiki/Mechanics

Not on a clock — Aurora is one of the random weather rolls, and it comes up about 7.1% of the time (Rain 28.6%, Lightning 21.4%, Rainbow 14.3% are all more likely). It lasts 2 minutes and gives growing crops a chance at the Aurora mutation. Every active server gets the same weather at the same time.

No fixed schedule.

Grow a Garden 2 has no egg shop — eggs come from guild weekly rewards, Lucky Swipe and the Auction. The Auctioneer rotates his lots (seeds, crops, pets, gears, crates, seed packs and eggs) on a Dutch auction where the price falls the longer you wait. The wiki gives the rotation as both 30 and 15 minutes, so no countdown is shown until that is settled.
