HATCH TIME · YOUR MEASURED DURATION
Steal An Egg Hatch Time Calculator: Countdown & Finish Clock
Use the duration you timed on one complete hatch, log when the egg went in, and read the remaining countdown plus the clock time each slot finishes.
Hatch inputs
Enter the hatch length you timed yourself, then how long the egg has already been in. Nothing is prefilled from an official table, because none is published.
How to use the countdown
Time one hatch from the moment the egg goes in to the moment it opens, then enter that duration. Add how long the current egg has been hatching, and the tool returns what is left.
The finish clock is computed from your device clock. It exists so you can plan a session around the moment the egg opens, not because the game publishes a server schedule.
Why there is no default length
Official sources publish no per-egg hatch table, so a filled-in default would be an invention. The tool leaves the field at zero and waits for your own timed value.
Community reports say eggs keep progressing while you are logged out, but the offline share is not verified here. Add only the minutes you actually observed, or leave the field as it is.
Formula & limits
The finish clock follows your own device timezone, so it is a session aid rather than a server schedule. Because no official hatch table exists, an empty length produces no countdown at all.
FAQ
Where does the hatch length come from?+
From your own measurement of one complete hatch. The official sources publish no per-egg hatch table, so the tool never supplies one.
Can I plan several eggs at once?+
Yes. Enter the hatch length, how long ago the batch started, and how many slots you run in parallel. The tool returns the remaining time and finish clock for each slot.
Does offline time count?+
Community reports say eggs keep progressing while you are logged out, but the offline percentage is not verified on this site. Add only the minutes you actually observed.
Why show a clock time as well as a countdown?+
A finish clock is easier to act on while planning a session. It is computed from your own device clock, so it follows your timezone rather than a fixed server one.
What if my egg finishes faster than the recorded length?+
Enter the shorter duration you measured. The tool uses whatever you type, and Reported or Unknown values are never substituted for your own observation.
