set date back now phone won't turn on

A C&P is appropriate here...

If it has NEVER been jailbroke, here are some standard repair procedures:

First, try a system reset. It cures many ills and it's quick, easy and harmless...

Hold down the on/off switch and the Home button simultaneously until you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.

If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. It could take well over an hour! Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod/iPhone and then select the Summary tab. Follow the on-screen directions for Restore and be sure to say "yes" to the backup and back up to the computer's iTunes (NOT iCloud) because it's more thorough. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod/iPhone. Again, say "yes."

At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod/iPhone. As before, say "yes." Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time. If that happens, only the apps that are part of the IOS will appear on your device. Corrective action is simple - choose manual "Sync" from the bottom right of iTunes.

If you're unable to do the Restore (or it doesn't help), go into Recovery Mode per the instructions here. You WILL lose all of your data (game scores, etc,) but, for the most part, you can redownload apps and music without being charged again. Also, read this.

Then you need to try the rest of the excellent instructions that Philly_Phan outlined.

And, in case you haven't already figured it out, don't do things just because your friend did it and it "seemed cool". Next time, it may be something serious that goes wrong.

I'm concerned about the "VERY hot" comment. Bite the bullet and confess to your parents. After you regain consciousness, ask them to take you to the nearest Apple Store.

Meg is correct. Do NOT take the battery out!

Good.

Good luck! I hope you get it sorted out.

If it's getting hot, don't plug it in tonight.

Probably better not plugging it in under any circumstances.
