When to germ seeds

Okay, it's getting to that time of year to start thinking of germinating the precious seeds. When do you germinate for outdoor planting?

what ya putting out?
if i was doing this i would be putting them out when they are about 4weeks old.
this year 2010 average temp for march will be low
april will be wet as will june
best time to put them out would be mid may
so germinating them would be about the 7th of april would be good
gives ya harvest date round about oct 14 or there abouts
but to be honest with the weather the way it is could be a bad year
