NORTHERN HEMISPHERE — The first day of summer typically falls around June 21. This year, it’s worth it to note that the precise time of summer solstice locally is 9:24 p.m. PST on Tuesday, June 20. It’s the day with the most hours of sunlight in the entire year.
According to The Farmer’s Almanac, the timing is not based on a specific calendar date and time. Rather, it depends on when the Sun reaches its northernmost point from the equator. The word solstice is from the Latin solstitium, from sol (sun) and stitium (to stop), reflecting the fact that the Sun appears to stop at this time, as it appears to again at the winter solstice.
Sunrise on this longest day of the year was at 5:39 a.m., and the Sun sets at 8:24 p.m., giving us in this area about 14 hours and 45 minutes of sun.
