On the celestial sphere, a solstice occurs when the Sun appears to reach its greatest northerly or southerly excursion relative to the celestial equator. Every year, around June 21 and December 21, two solstices occur. The solstices and equinoxes are used in many nations to determine the seasons of the year.
The term solstice can also refer to the day when this occurs in a broader meaning. For any place other than the Equator, the day of a solstice in either hemisphere has either the most or least sunlight of the year (summer solstice) for any place other than the Equator. "June solstice" and "December solstice," referring to the months in which they occur every year, are alternative phrases that do not imply which hemisphere is in question.
The word solstice is derived from the Latin sol ("sun") and sistere ("to stand still"), because at the solstices, the Sun's declination appears to "stand still"; that is, the seasonal movement of the Sun's daily path (as seen from Earth) pauses at a northern or southern limit before reversing direction.
Since New Zealand sits in the southern hemisphere we have winter solstice on 21st June at 3:31pm and summer solstice on 22nd December at 4:58am.
