(CNN) -- For six months now, the days have grown shorter and the nights have grown longer in the Northern Hemisphere -- but that's about to reverse itself.Winter solstice, the shortest day of 2019, will be Saturday, December 21. Or it will be Sunday, December 22. Which day is it for you? It all depends on your time zone.CNN meteorologists Dave Hennen, Judson Jones and Brandon Miller help us understand the science and timing behind the solstice. And then we'll discover some traditions and celebrations around the world that could inspire a travel adventure.The science and timing behind a winter solsticeThe winter solstice marks the shortest day of the year in the Northern Hemisphere, when the sun appears at its most southerly position, directly overhead at the faraway Tropic of Capricorn.It's the reverse in the Southern Hemisphere. There, it marks the longest day of the year -- and the beginning of summer in places such as Argentina, Namibia and New Zealand.When exactly does it occur?The solstice usually takes place on December 21. The time that the solstice occurs and the day itself shifts because the solar year (the time it takes for the sun to reappear in the same spot as seen from Earth) doesn't exactly match up to our calendar year.If you want to be super-precise in your observations, the exact time of the 2019 winter solstice will be 4:19 Universal Time on Sunday. Here are some examples of when that will be for local times around the world:-- Tokyo: 1:19 p.m. Sunday-- Dubai: 8:19 a.m. Sunday-- Rome: 5:19 a.m. Sunday-- Dakar, Senegal: 4:19 a.m. (same as Universal Time)-- Philadelphia: 11:19 p.m. Saturday-- Seattle: 8:19 p.m. Saturday-- Honolulu: 6:15 p.m. SaturdayIf you don't live in one of these time zones above, the website EarthSky has a handy conversion table for your time zone. You might also try the conversion tools at Timezoneconverter.com or WorldTimeServer.com.What causes the winter solstice to even happen?Because the Earth is tilted on its rotational axis, we experience seasons here on Earth. As the Earth moves around the sun, each hemisphere experiences winter when it's tilted away from the sun and summer when it's tilted toward the sun.Wait. Why is the Earth tilted?Scientists are not entirely sure how this occurred, but they think that billions of years ago, as the solar system was taking shape, the Earth was subject to violent collisions that caused the axis to tilt.What other seasonal transitions do we mark?The equinoxes, both spring and fall, occur when the sun's rays are directly over the equator. On those two days, everyone has an equal length of day and night. The summer solstice is when the sun's rays are farthest north over the Tropic of Cancer, giving us our longest day and summer in the Northern Hemisphere.Winter solstice traditions and celebrationsIt's no surprise many cultures and religions celebrate a holiday -- whether it be Christmas, Hanukkah, Kwanzaa or pagan festivals -- that coincides with the return of longer days.Ancient peoples whose survival depended on a precise knowledge of seasonal cycles marked this first day of winter with elaborate ceremonies and celebrations. Spiritually, these celebrations symbolize the opportunity for renewal, a shedding of bad habits and negative feelings and an embracing of hope amid darkness as the days once again begin to grow longer.Many of the ancient symbols and ceremonies of the winter solstice live on today.Here are five extraordinary destinations where you can experience something magical during winter's relentlessly long night:UNITED KINGDOM: Cornwall and StonehengeBetter known for pirates than the solstice, the town of Penzance on the southwest coast of England has revived a delightful array of Cornish solstice events leading up to winter solstice. The Montol Festival is a fun mix of pagan customs and more recent Christmas traditions that were once common throughout Cornwall.Early in the week, join in caroling and other events. On the solstice, referred to here as Montol Eve, get your dancing card ready for the Guise, a community dance in which people dress in masks and other "topsy-turvy" disguises based on a 19th-century tradition of the rich dressing in rags while poorer citizens effected a "mock posh" look.You can also don your finery for torchlit processions. The merrymaking only continues when the revelers disperse to pubs around town.With some planning, it's also possible to incorporate a trip to Stonehenge, the UK's most famous site for solstice celebrations. On the winter solstice, visitors have the rare opportunity to enter the towering, mysterious stone circle for a sunrise ceremony run by local pagan and druid groups.The trip from Penzance to Stonehenge takes less than four hours by car, making it entirely feasible to spend the night in Salisbury, the nearest town to Stonehenge, and rise before dawn for the ceremony among the stones.SWEDEN: Santa Lucia, yule and aurora borealisSweden is rich with solstice traditions.

 ESPN The Magazine is celebrating its 20th anniversary by releasing lists of the best teams and athletes of the last 20 years. Needless to say, there isn't a lot of San Diego on the list -- with the exception of a No. 4 ranking for NASCAR driver Jimmie Johnson on the "Most Dominant Athletes" list. As it happens, my career in San Diego sports media began in 1998, so I thought I'd take it upon myself to come up with a list of the best San Diego teams of the past 20 years. Unlike ESPN, which came up with complicated metrics to determine their lists, mine is completely subjective.
