(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.

(AP) - Rocker Ted Nugent says the Florida students calling for gun control have "no soul" and are "mushy brained children."The 69-year-old made the comments Friday while defending the National Rifle Association as a guest on the Joe Pags show, a nationally syndicated conservative radio program.Nugent, a longtime member of the NRA's board of directors, said survivors of the Feb. 14 shooting at Marjory Stoneman Douglas High School are wrong to blame the NRA and its members for mass shootings.RELATED: Fox News host Laura Ingraham faces advertiser backlash after mocking Parkland survivor"These poor children, I'm afraid to say, it hurts me to say, but the evidence is irrefutable: They have no soul," Nugent said. He added that the gun control measures the students support amount to "spiritual suicide" and "will cause more death and mayhem."A representative for Nugent did not respond to a request for comment on Saturday.Some Parkland students responded on social media and demanded an apology."If only he saw all the tears. If only he had to look into the eyes I've looked into. If only he saw what this did to all of us," junior Cameron Kasky said on Twitter. "And here the NRA is, receiving more fear-based donations than ever. Talk about 'no soul.' This guy better apologize. Seriously."RELATED: Parkland school shooting: Memorial at Stoneman Douglas High School dismantledSenior Kyra Parrow said it's funny that the NRA rails against bullying while Nugent was "being a 5 year old acting like a bully" to her and her classmates.Nugent made the comments the same day several advertisers dropped Fox News personality Laura Ingraham after she mocked a survivor of the Parkland shooting online.Ingraham said Friday she will take a weeklong "Easter break" with her children while guest hosts fill in on her show, "The Ingraham Angle."She drew backlash Wednesday when she shared an article on Twitter saying student David Hogg had been rejected by four colleges and was whining about it.

 A Florida man has been charged with 144 counts related to cruelty to animals.The State Attorney's Office has charged 51-year-old Robert David Starkweather after investigators found what 77 cows, 48 calves, and 2 donkeys found on his Hendry County farm.Photos taken by the local Sheriff's Office showed animals as bags of bones."That's got to be the most horrific fate, worst way to go," local animal rescuer Carey Kendzior said. "These are massive animals and it would take months to let it get to that point of cruelty and neglect. There's no excuse."Rescuers came too late for some. There were 13 animals found dead upon arrival."I don't care who you are. No reason for you to be in charge of animals," Kendzior said.The Hendry County Sheriff's Office investigated the case with assistance from both the Lee County Sheriff's Office and the Collier County Sheriff's Office. The animals were sized and were taken from the property and moved to another location.One calf died and five had to be euthanized due to their poor health conditions after being looked at by a veterinarian.Dr. Laura Braun is a vet in Fort Myers. Braun was disturbed when she saw the photos. "That's not how cattle are supposed to look, not even close," she said.Starkweather will be arraigned on May 17. 1302

You may not see them popping up in dispensaries yet, but Oakland just allowed the use of "magic mushrooms" and other natural psychedelics.On Tuesday, Oakland's City Council voted unanimously to decriminalize the use of 'shrooms and other natural psychedelic or hallucinogenic drugs, including cacti, becoming the second city in the country to take this step.The drugs still aren't necessarily legal, but the resolution means police cannot impose criminal penalties for using the natural drugs or use any city funds to investigate or enforce the criminal penalties. Even people currently being prosecuted for these kinds of drugs are now off the hook, according to the resolution. 691
