How long can Hard boiled eggs, kept basically at room temp, be kept and still be eaten? Basically we are talking about dyed Easter Eggs here. ---

Hard boiled eggs are usually good for up to one week AFTER they have been hard boiled,provided they are still in the shell and have been kept refrigerated. ---

Well, according to [WhatsCookingAmerica](http://whatscookingamerica.net/eggs.htm), one week in the refrigerator. At room temp, obviously less time. Personally, I wouldn’t touch one after a day. ---

Ok, I’m bored. I’ll bite. Hundred year old eggs, also called thousand year old eggs, are just duck eggs preserved/cured inside a coating of wood ash and lime basically. I believe it only takes about 100 days really. ---

The “hundred year eggs” only last for two weeks after they’re removed from the salt. [allrecipes.com](http://www.allrecipes.com/encyc/terms/H/6958.asp) > [@](#): > > They will keep at room temperature (under 70°F) for up to 2 weeks or in the refrigerator up to a month. ---

> [@](#): > > \*Originally posted by swanky \* > \*\*One year we had an egg that was lost underneath the front seat of the car. It rolled around for a few months before it was found in July. The yolk had dried and hardened like a brick and in all that rolling it had picked up all of the white, so when opened there was a shell and a yolk and nothing filling the white area. Stunk. \*\* Were you bored? 😕 Why the heck did you crack open an egg that had been rolling around the car for a few months? :eek:
