July 15 is the 196th day of the year in common years and the 197th day in leap years, leaving 169 days remaining in a non-leap year. The date belongs to the modern Gregorian calendar and sits in the middle of July, a month commonly associated with summer in the Northern Hemisphere and winter in the Southern Hemisphere.

Seasonal and calendrical position

The day usually falls under the astrological sign of Cancer and is typically several weeks after the summer solstice in the north. In many cultural calendars it is a mid-summer date, often used as a reference point for agricultural planning, school holidays and seasonal festivals. Its place in the year shifts by one day in leap years, which is why it is the 197th day when February has 29 days.

Observances and notable commemorations

  • World Youth Skills Day — observed by the United Nations on July 15 to raise awareness of the importance of technical and vocational education and training for youth employment.
  • Saint Swithin's Day — in parts of the Anglican tradition July 15 is associated with Saint Swithin and old weather lore about the following 40 days of weather.
  • Various national and local events, anniversaries and civic commemorations take place on this date in different countries; some observances are fixed while others are movable.

July 15 has also been the date for many historical, cultural and scientific events over time. It is commonly the anniversary for births and deaths of artists, political figures and other public figures, and it features in the timing of seasonal festivals and public holidays in different traditions.

Because it is a fixed date, July 15 is used in record keeping, anniversary planning and long-range scheduling. Its significance varies widely by region: for some it is a day of formal observance, for others a routine summer day. When consulting historical records or planning events, it is useful to note whether the year in question was a leap year, since that affects the day-of-year count.
