In Odessa, Sunday marks a significant point in the year. For those living in the Northern Hemisphere, it is the longest day of the year. This day is known as the summer solstice, which signals the beginning of astronomical summer.

The summer solstice has a different impact on the other half of the world. In the Southern Hemisphere, Sunday is actually the shortest day of the year. Further information about the summer solstice can be found through the Odessa American, which provides a guide to this phenomenon.
