Hatch Dates & Incubation

Understand expected hatch dates and hatch windows.

Frequently asked questions

How is the Expected Hatch Date calculated?
HerpClutch uses the recorded Lay Date and the configured incubation period to calculate an Expected Hatch Date. It is a planning estimate; actual hatch timing can vary.
What is a Hatch Window?
A Hatch Window is an expected range of dates a Clutch may hatch within, based on configured minimum and maximum incubation values.
Are hatch dates guaranteed?
No. Expected hatch dates and Hatch Windows are planning estimates based on the information you record. Actual hatch timing may vary.
Can incubation settings be changed?
Incubation values are associated with the Species. Changing the Lay Date or the incubation information used by a Clutch can affect the expected hatch calculations.
How do Hatch Reminders work?
HerpClutch can use local reminders to notify you as an expected hatch period approaches, when notifications are enabled. Delivery depends on your device's notification permissions.
