The longest day of the year at the Northern Hemisphere kicks from the official calendar beginning of summer and with it, the bounty of the harvest. Therefore it should come as no surprise that the solstice is connected to fertility -- the human and plant variety -- at destinations across the world.
CNN Travel investigates a number of those sensual, long-standing summer customs. But first, we will have a peek at a few of the sciencefiction.
Summer solstice: Q&A
Query: I enjoy accuracy. Just when is the summer solstice in 2021?
Response: Sorry to complicate matters for you, however, the date you observe this season depends on which side of the world you reside.
It'll occur just at 03:32 UTC (Universal Coordinated Time) on Monday, June 21. Your time period in connection with UTC decides the date that the solstice occurs for you. Here is how 03:32 UTC lines up with local time in pick areas around the planet:
-- Tokyo: 12:32 p.m. Monday
-- Mexico City: 10:32 p.m. Sunday
-- Calgary, Canada: 9:32 p.m. Sunday
-- San Francisco: 8:32 p.m. Sunday
-- Honolulu: 5:32 p.m. Sunday
the web site TimeandDate includes a useful tool to allow you to figure out the period for where you live.
Query: It is the longest day of this year -- and it occurs all around the world?
Response: Nope. It is the longest day Just in the Northern Hemisphere. It is the shortest day of the year south of the equator. Residents of the Southern Hemisphere -- in areas like Argentina, South Africa and New Zealand -- are all going to welcome three weeks of winter.
Along with the gaps in how much daylight you become become very striking as you get nearer to the rods and further from the equator. For example, residents of northerly St. Petersburg, Russia, will find a 3:35 a.m. sunrise and nearly 19 hours of lighting. The night does not get that dim.
In Singapore, a Northern Hemisphere city-state but only barely over the equator, folks hardly see the difference. They receive a measly extra 11 minutes .
As for those poor penguins in Antarctica protecting their eggs if they could speak, they can tell you a good deal about living in 24-hour shadow.
Issue: Why not we simply get 12 hours of daylight annually?
Response: People throughout Earth really did get almost equal doses daily and nighttime back throughout the spring equinox. However, the amount of sun we get in the Northern Hemisphere has been growing daily ever since. Why?
That is because the Earth is aligned in an axis, an imaginary pole moving through the middle of the planet. However, this axis tilts -- in an angle of 23.5 degrees.
"As Earth orbits the sun [once annually ], its tilted axis always points in precisely the exact same direction. So, through the entire year, different pieces of Earth receive the sun's direct rays," according to NASA.
Once the sun reaches its apex in the Northern Hemisphere, that is the summer solstice.
At that moment,"the sun is directly above the Tropic of Cancer, which can be situated at 23.5° latitude North, also runs via Mexico, the Bahamas, Egypt, Saudi Arabia, India and southern China," in accordance with the National Weather Service.
