Grow a Garden Harvest Moon P4: Start Time, Countdown & What’s Coming

Updated August 22, 2026 By AllThingsHow Staff 34K playing now

Grow a Garden saves its biggest recurring moment for Saturday afternoons, and the current headliner is Harvest Moon P4, the closing chapter of the game’s Harvest Moon run. It arrives with a fresh set of activities, rewards, and cosmetics for a farming title that regularly keeps over 25,000 players tending plots at the same time and has pulled in well past 35 billion visits since it launched.

Harvest Moon follows the same steady rhythm as the parts before it: a weekly cycle that lands in the game’s Saturday event slot. The next run begins Saturday, August 29 at 4:30 PM ET, and the countdown to it, along with the usual start time, sits on the card below.

How Harvest Moon’s Saturday slot has run

The Harvest Moon event has landed on a weekly basis, opening each Saturday at 4:30 PM ET. It has run 3 times so far, with Part 4 billed as the finale of the run. There is a single scheduled window each week rather than a spread of daily slots, so the trick for players outside North America is simply knowing when 4:30 PM Eastern falls where you are. Here is that one start time converted across the major regions:

  • New York (ET): 4:30 PM Saturday
  • Los Angeles (PT): 1:30 PM Saturday
  • London (BST): 9:30 PM Saturday
  • Central Europe (CEST): 10:30 PM Saturday
  • India (IST): 2:00 AM Sunday
  • Japan (JST): 5:30 AM Sunday
  • Sydney (AEST): 6:30 AM Sunday

What’s new in Harvest Moon P4

As the finale of the Harvest Moon arc, Part 4 broadens what the earlier chapters introduced and adds a batch of new content to chase during the window. Expect:

  • New activities layered on top of the existing Harvest Moon tasks
  • A new shovel skin to earn
  • Fresh pets to collect
  • New plants to grow
  • Additional event rewards
  • Quality-of-life improvements to the wider game

Tips for catching it

The whole event hinges on that one weekly slot, so a reminder helps — especially for players in India, Japan, and Australia, where 4:30 PM ET lands in the small hours of Sunday morning. Progress-style rewards are best approached across the whole run rather than crammed into a single sitting — but since this is the closing chapter of Harvest Moon, there’s no guarantee of another Saturday run once this one wraps. Hop in near the start time to give yourself the longest stretch inside the window.

How it fits Grow a Garden’s rhythm

Grow a Garden keeps a busy events calendar, and Harvest Moon is its weekend anchor. Midweek, Watering Wednesday has been part of the mix too, and a broader Next Update sits on the horizon with its own additions. With Watering Wednesday’s midweek runs and Harvest Moon P4 closing out the Saturday slot this weekend, the game has kept regulars busy with a steady pattern to follow.
