Solstices and Equinoxes Summer Solstice = June 21 – Sun rises North of East

Solstices and Equinoxes Summer Solstice = June 21 – Sun rises North of East & Sets North of West – 15 Hours of Daylight – Sun’s rays are direct at the Tropic of Cancer

Winter Solstice = December 21 – Sun rises South of East & Sets South

Winter Solstice = December 21 – Sun rises South of East & Sets South of West – 9 Hours of Daylight – Sun’s rays are direct at the Tropic of Capricorn

Sun’s Path: Equinoxes Fall Equinox = September 22 – Sun rises Due East &

Sun’s Path: Equinoxes Fall Equinox = September 22 – Sun rises Due East & Sets Due West – 12 Hours of Daylight – Sun’s rays are direct at the Equator

Spring Equinox = March 21 – Sun rises Due East & Sets Due West

Spring Equinox = March 21 – Sun rises Due East & Sets Due West – 12 Hours of Daylight – Sun’s rays are direct at the Equator *Notice they are the SAME except for the dates*
