Examples of Solstice and Equinox Dates

📚 Quick Study Guide

• 🌍 Solstices: These mark the times when the Sun reaches its highest or lowest point in the sky relative to the equator. We have two solstices each year.
• ☀️ Summer Solstice: Usually around June 20-22 in the Northern Hemisphere, marking the longest day of the year. The Southern Hemisphere experiences its winter solstice at this time.
• ❄️ Winter Solstice: Usually around December 21-23 in the Northern Hemisphere, marking the shortest day of the year. The Southern Hemisphere experiences its summer solstice at this time.
• 🍁 Equinoxes: These occur when the Sun crosses the celestial equator, meaning day and night are of equal length (approximately 12 hours each).
• 🌱 Spring (Vernal) Equinox: Usually around March 19-21 in the Northern Hemisphere. The Southern Hemisphere experiences its autumn equinox at this time.
• 🍂 Autumnal Equinox: Usually around September 22-24 in the Northern Hemisphere. The Southern Hemisphere experiences its spring equinox at this time.
• 📅 Important Note: These dates can vary slightly each year due to the Earth's elliptical orbit and leap years.
