How long do Firelizard eggs take to mature?

[Kastaka]

So, I've got this firelizard egg - how long can I leave it before it has to hatch? A sevenday? A month? Two months?

Firelizard eggs have about a month after they are laid before they hatch.  They can't be moved for the first two sevendays until they harden, so you've got about two sevendays when they can be moved, traded, etc.  So if you got the egg from a trader/merchant you've probaby got a little over a sevenday. If you found it you've got anywhere from two sevenday to a couple days.
