June 21, 2021 is within 1 second of being the longest day of the year and officially the first full day of Summer. (Technically summer began last night)
With the sunrise at 5:48 am and sunset not until 8:35 pm in San Francisco that gives us a full 14 hours, 46 minutes and 54 seconds of daylight to have fun with.
