Read the Watch First
The in-game watch remains the source of truth. This tool only converts and remembers the windows you enter.
Manual forecast planner · no fake live feed
Heartopia Weather Planner
Open the weather screen on your in-game watch, copy the server-time window here, and convert it to your own clock. Your offset and weather plan stay in this browser; the tool does not predict weather or send your schedule to a server.
1. Calibrate Server Time
Enter both clocks at the same moment. This turns confusing server hours into your local date and time.
Local conversion is off. Add the current server time to calibrate it.
2. Add a Weather Window
Use the date and 24-hour times displayed by the in-game forecast. A window ending before it starts is treated as crossing midnight.
Saved Weather Windows
Maximum 50 windows. Duplicate date, time, and weather entries are rejected.
