Chicago-henge: When and how to see this unique phenomenon

CHICAGO (WLS) – Twice a year, a unique phenomenon called "Chicago-henge" – based in Stonehenge – can be observed in Chicago.

Look down any road east / west in the loop and you will see the sunrise or sunset on the horizon. This is a beautiful view with the tall buildings framing each side.

The reason is the perfect east / west layout of the Chicago and Equinox roads. Thanks to the planners for having built such a perfect grid!

The equinox occurs when direct sunlight is directly on the equator. "Equinox" means equal day and night. Thus, every place on Earth has about 12 hours of daylight and 12 hours of night.

The vernal equinox (vernal equinox) and the autumnal equinox (autumn equinox) are the only two times of the year where you can see "Chicago-henge ".

The spring equinox is between March 20th and 23rd. This year, spring begins March 20 at 4:58 pm

The autumnal equinox falls between September 20th and 23rd. This year's fall starts on September 23rd at 2:50 pm
