When does "7-day" trial exactly mean?

[Stealth3si]

If an offer says "7-day trial" in which I sign up on the 10th, does that mean the last day of the trial lands on the 16th (or 17th) since the 16th is the seventh day of usage?

What are people's experiences with trial offers in terms of the date periods?

Mine are usually seven days after the sign-up date (the 17th in your case)

Plus if you receive a confirmation email, it may state what day your trial period ends, and your billing begins.  Or if you sign into your account on that company's site, it might be somewhere in there.
