Chicago turns MAGICAL PINK as the first day of Spring begins

Equinoxes, when the sun lands equally on both hemispheres, mark the start of spring and autumn.

However, temperatures were not quite spring-like on Sunday, with sunny skies and highs in the low 40s

The date of the summer solstice marks the day of the calendar year with the highest amount of daylight hours.

From the vernal equinox up until the summer solstice, daylight hours will increase as dark-sky hours decrease.

On the first day of spring, the day of the vernal equinox, daytime and nighttime hours are roughly equal, just as they are during the autumnal equinox in late September

The vernal and autumnal equinoxes mark the beginning of spring and fall, while the winter and summer solstices define the astronomical start of those seasons respectively.

Although meteorological seasons are defined as periods of three months , astronomical season are aligned with biannual equinoxes and solstices.

After a frigid Saturday and a sunnier, milder finish to the weekend, the seasons officially changed in Chicago on Monday afternoon
