In Singapore, which is less than miles north of the equator, the number of daylight hours varies by only 10 minutes throughout the year. At high latitudes however, such as at Inverness in northern Scotland , the difference is more like 12 hours between midwinter and midsummer.
The benefit of long days in summer always being matched by long periods of darkness in winter: 18 hours of daylight in midsummer; only six and a half hours in midwinter. While the The orbit varies by about three million miles, the earth being closest to the sun in the first week of January and furthest away in the first week of July. It is worth remembering that even when daylight hours are limited i.
A top tip for anyone seeking winter sun : if you travel south from the UK in winter you are not only likely to experience warmer weather but longer days as well. On Christmas Day, while London receives nearly an hour's more daylight than Edinburgh with just under eight hours, Benidorm sees around and nine and half hours, and Maspalomas in Gran Canaria enjoys nearly With longer days in summer the sun naturally rises earlier and sets later, and vice versa in winter.
As the earth is roughly symmetrical in shape the longer period of daylight is split also roughly between a more daylight at the beginning of the day , matched by b more daylight at the end of the day.
However the two are not matched exactly because of: a the axial tilt of the earth , and especially b its eccentric orbit around the sun. The eccentric orbit means that the length of day as measured from solar noon on one day to solar noon on the next varies slightly throughout the year. From January to the end of March days are somewhat longer when measured this way of course only by a tiny amount. In the middle of February it takes about 15 minutes longer from one solar noon to the next when compared with the time at the winter solstice.
This is not because the rotation of the earth has slowed - this is always constant - it is because both the earth and the sun are moving relative to each other. The sun sets faster at the equator than at higher latitudes - this is because the speed of rotation of the earth is faster at the equator - approximately 25, miles in 24 hours at the equator compared with 11, miles in 24 hours at the Arctic circle.
Later in the year, around the end of October, days are 16 minutes shorter when compared with the clock. This caused widespread confusion, especially in transport and broadcasting. Following the oil embargo, the US Congress extended the DST period to 10 months in and 8 months in , in an effort to save energy. From to , the country observed DST for about 7 months each year. Sign in. Next change:. Need some help? I absolutely hate Daylight Savings Time!
We need to stay with the real thing: sun time. If you want different hours for your own business during the summer then post those different hours and dates. The belief that we gain one hour of daylight is illusionary. The one-hour gain is lost in the evening and vice versa with Standard time. For those who work evenings or night-time shifts, the sunrise or sunset causes glare for those who drive sorry ecologists to and from work.
This results in a greater number of accidents until the drivers get used to the blinding light. By staying on one - either Daylight or Standard time, drivers would gradually acclimatize themselves to the different grades of sunlight. I believe the rooster crows at sun-up and that is when the day begins regardless of the hour showing on the clock. Do we change the clocks because we are human and think we know more about nature than the animals?
Then why do we watch nature to make predictions? Throw the clocks out the window. They are controlling our lives. I don't like changing time.
Someone needs to step up to the plate and get rid of this detrimental time change twice a year. It's ridiculous. For everyone else, farmers especially, this was a horror show and it continues to be one. We love the extra daylight in the mornings. Hard enough to get up, but in the dark??? Make this the last time and this time when we go back to normal, leave it be!!! I wish we didn't observe it , it messes with everyone's sleep circadian rhythm too much, health wise I do not believe it is good for any of us.
I usually start the Thursday before the change mentally in my head adjusting and switch my clocks on Friday nights to help me and by Sunday I am fine. I don't care which time they choose, but one needs to be picked that benefits people the most.
The practice of changing our clocks twice a year is extremely detrimental to our physical health. Our bodies were not meant to change the circadian rhythm often. I live in Minnesota, so we already have extremely long periods of darkness in the winter.
So, as an early riser, I cannot in any way support efforts to impose Daylight Saving Time year-round. In fact, I personally would much rather have year-round Standard Time though of course that would mean summer sunrises before 4 A. Either way, I'm really tired of the twice annual changing of the clocks. Neither does Hawaii. The only time it was frustrating was in business. Quite literally the east coast shuts down at or 2pm AZ time because they are 3 hours ahead of us. In these current days..
But in AZ in the summer.. So we will continue as is while the rest of you worry about the clock. Just stop using DST altogether. Give me a he farmers a break. If the fools in this country insist on having DST, at least go back to the start on the last Sunday in April and end on the last Sunday in October. Hello, November 7, is a Thursday, not Sunday. That would be November I had a few moments of confusion! Why not put the entire world on Greenwich Median time? Every country every clock stays on a 24 hour military clock per Greenwich.
Schedules and appointments are on the same clock throughout the United States the world. My boss says to be at work at xx:xx I'm there. Over an hour of lost and regained sleep? Holy cow I'm glad I never lived such a rigid, structured life that my sleep patterns were never once interrupted, not even 2 hours a year.
I've traveled all over the world and back, all over the country and back, nd there's nothing worse than jet lag returning from overseas. Actually, there is; Lousy hotel sleep following long days turned into long weeks of stressed business meetings covering 4 cities in 4 areas of the country, long nights of business entertaining.
Fitful sleep close to the elevator or the dumpster even in the finest of hotels, waking up never knowing exactly where you are for the first few minutes of the day. Eventually adapted to business trave, loved personal, foreign travel, loosing sleep part of the journey. So, you figure it out or else become eadicated from your own history. People lighten up. It's 2 hours of the year. The only two groups who have a true and real gripe are the origional inhabitants of this land, the Indigenous Peoples, and today's Smaller Farmers; Those who live, work with and honor the land and nature.
For crying out loud.. Pick one and stick with it.. Although, myself a city slicker, it's the farmers who sustain us. I side with whichever method of time-keeping will soothe the animals, keep the fields tended and help the farmers in any way possible.
No one is stepping in to save the smaller farmers, from those they feed, sacrificing one hour a year isn't too big of a sacrifice. Boo hoo. I agree leave to standard time instead of daylight savings time because it messes our health and mood and sleepy. Skip to main content.
