On July 2, which is the 183rd day of a year that has 365 days, a typical calendar year will have passed its halfway point. On July 1 of a leap year, which has a total length of 366 days, one is exactly halfway through the year.
Noon on the day in question marks the exact point in time that represents the year’s median length, whichever it may be. This does not take into account the fact that according to the Western or Gregorian calendar, one year is slightly longer than 365 days but shorter than 366 days. This is because the calendar is based on the movement of the sun. According to this particular calendar, the first or second of July is only the middle of the year. The year according to the lunar calendar only has 354 days in it.
