Answer:
leap year have 366 days
Answer:
1:A leap year is a calendar year that contains an additional day added to keep the calendar year synchronized with the astronomical year or seasonal year.
2:The summer solstice, which happens on June 21 or 22 each year, has the longest daylight time. It's also the first day of summer. The winter solstice, on December 21 or 22, has the shortest daylight time, and officially kicks off winter. This is only true in the Northern Hemisphere, though.
3:An equinox is commonly regarded as the instant of time when the plane of Earth's equator passes through the center of the Sun. This occurs twice each year, around 20 March and 23 September. In other words, it is the moment at which the center of the visible Sun is directly above the equator.
4: Because of the tilt of the earth on its axis. When the North Pole is tilted towards the Sun, the northern hemisphere experiences summer solstice. ... That is why, When it is summer in the northern hemisphere, it is winter in the southern hemisphere. It's all because the Earth is tilted on its axis.
5:The seasons are caused by Earth's tilt. As Earth orbits the Sun, for roughly six months during the year, the northern or southern axis - the poles- are tilted towards sun. During these times, the hemisphere tipped toward the Sun experiences summer, while the hemisphere tilted away from the sun experiences winter.
