This is what I use under my seedling tray.When to start depends on WHAT you start and when your planting season for those crops starts.
If you use a heating pad as a seed starter, make sure it is the kind that can be washed (the PAD, not just the cover) or make real sure that no water can get to it. Water and electricity don't play nice together.
I grow year round indoors using hydroponics so I can start what ever I want when ever I want.
What ever my wife and I don't eat gets fed to the chickens.
