wow, that would suck.....
I know in some areas, if you have children, they have to give you up to 90 days. I used to live in a rental and they evicted a girl with like 5-6 kids and she went to court and they told them they have to give her 90 days because she had kids and a residence that size wasn't cheap or easy to find, so they gave her 90 days.
In MOST areas, it is a standard 30 days, 24 days seems like an odd number of days unless it's a rental and they sold the place from under you, which I have seen before.
