Halloween is on the same date every year - October 31st.
In 2013 this is a Thursday.
There's no official start time. Traditionally it's after it is dark outside and no one wants to be the first or alone so usually kids watch for other kids and then hit the streets.
Halloween officially begins at 12:00 AM midnight on October 31, 2014. Since Halloween is an official U.S. holiday, there is no official start time in Waukesha. Most of the kids, however, will be trick or treating in late afternoon and early evening hours.
The next time that Halloween will fall on Friday is in the year 2025. The last time it was on a Friday was 2014.
Halloween hours are 4:30-7:00
The next Halloween on a Friday after 2014 is not until 2025.
