The June solstice – your signal to celebrate summer in the Northern Hemisphere and winter in the Southern Hemisphere – will be celebrated June 21, 2019, at 15:54 UTC. That’s 11:54 a.m. Eastern Time in North America on June 21. For us in the Northern Hemisphere, this solstice marks the longest day of the year. Early dawns. Long days. Late sunsets. Short nights. The sun at its height each day, as it crosses the sky.
Since most us are at work at 11:54 am, let's plan on meeting later that day - 6pm to 8pm - to kick off the summer with some good geocaching stories, swap trackables and just have plain old fun with people who share the hobby. No purchase necessary for that!
