How does forensic know how long a body has been dead?

Question

I’ve always been curious on how they know how long a body has been dead for? For example, if they say “the body has been dead for 2 hours”, how come it’s not 2 days, weeks, etc..?

edit: spelling

this a an awesome subject, and there are so any ways, like what parts have decomposed, or muscle rigidity, or blood pooling, but one of my favorites is bugs. they can see the maggots or the flyes on the body and tell how land they’ve been dead with the age of the maggots.
