From an , summer begins with the summer solstice—the longest day of the year—and ends with the autumnal equinox, when day and night are roughly equal. In the Northern Hemisphere, the solstice occurs around June 20 or 21, and the equinox around September 22 or 23. Therefore, astronomical summer spans the latter half of June, all of July and August, and the first part of September. In the Southern Hemisphere, these dates are reversed: summer runs from late December through March, with the solstice around December 21. In the Northern Hemisphere, the solstice occurs around

For example, in the United States and much of Europe, the "summer break" for schools typically spans from late May or early June until late August or early September, effectively treating June, July, and August as the summer months. Conversely, in Australia and New Zealand, summer is culturally tied to Christmas and New Year’s, with December, January, and February being the season for beach trips and barbecues.
