Overview
June 22 is a date in the Gregorian year that falls early in the second half of June. In common (non-leap) years it is the 173rd day of the year and in leap years it is the 174th day; in both cases there are 192 days remaining until the end of the year. This placement makes June 22 one of the mid‑year dates that often lies close to the June solstice.
Calendar and seasonal context
The date appears in calendars based on the Gregorian calendar. Because the timing of the June solstice varies between June 20 and June 22 in different years, June 22 sometimes follows immediately after that astronomical event. In the northern hemisphere it falls in late spring or early summer (commonly within the sign of Cancer in tropical zodiac systems), while in the southern hemisphere it is in late autumn or early winter.
