Welcome to Halloween 2016. Yes, trick or treating is tonight — the time to get your bags filled with candy.

It’s a school night this year so times are important.

What time does trick or treating start tonight?

Sunset for most trick-or-treaters.

Usually trick or treaters don’t want to go out before dark so sunset is usually the time to begin. This year, sunset in the central U.S. will be at about 6:05 p.m. and it of course varies city-by-city so check the sunset forecast for your city here and get prepared because when that sun sets, it is time to go trick or treating.

But many younger trick or treaters like to get started early, especially when Halloween falls on a school night. So many will begin trick or treating neighborhoods at 5 p.m. this evening. That’s an appropriate time and the sun will be setting soon after.

What time does trick or treating end on Halloween this year?

A good rule of thumb and something some cities even enforce is that trick or treating ends at 8 p.m. or no later than 9 p.m. That gives two to three full hours of trick or treating. Its rude to knock on doors much later than 9 p.m. unless they have all lights still on. So that’s the trick or treating times for this Halloween 2016 (Monday, October 31).

So, from about 6 p.m. to 9 p.m. are the best hours for getting candy or beginning at 5 p.m. until 8 p.m. for younger children.
