The Best Time of Day to Do Just About Anything according to this cool new website a good friend reccommended!!!

The Best Time of Day to Clean the House
4 p.m.
You’re more likely to whistle while you window wash (and not kick over the bucket) if you do it in the late afternoon. That’s when hand-eye coordination is at its peak and mood levels are high, says Michael Smolensky, a professor of environmental physiology at the University of Texas School of Public Health at Houston and author of The Body Clock Guide to Better Health (Owl Books, $11, www.amazon.com).

The Best Time of Day to Take a Nap
1 p.m. to 2:30 p.m.
Doctors used to think afternoon sleepiness was the result of a big lunch. “But we’ve found that in the early afternoon there’s a dip in body temperature, which causes sleepiness,” says Smolensky. Just as a similar decrease encourages you to shut down at bedtime, this midday dip can make you crave a siesta. An ideal nap, he says, should last 15 to 20 minutes. More than 30 and you may end up with sleep inertia — and feel even more groggy when the nap’s over.

The Best Time of Day to Go to the Doctor
8 a.m. to 9 a.m., or 1 p.m. to 2 p.m.
You’ll spend less time in the waiting room if you book the first appointment of the morning or the first after lunch, says Patricia Carroll, R.N., author of What Nurses Know and Doctors Don’t Have Time to Tell You (Perigee, $15, www.amazon.com): “Doctors start fresh in the morning and catch up when the office is ‘closed’ for lunch.”

The Best Time of Day to Take a Multivitamin
Breakfast time
Taking your supplements with a meal is important because “vitamins are components of food, and whether water soluble or fat soluble, they are absorbed better with food,” says Shari Lieberman, Ph.D., a New York City and Hillsboro Beach, Florida, nutrition scientist and a coauthor of The Real Vitamin & Mineral Book (Avery Publishing, $13, www.amazon.com). Breakfast is the meal of choice. Because most people have it at home (whereas lunch and dinner are often eaten elsewhere), making the morning meal your time for vitamin-popping will help you stick with the habit.

The Best Time of Day to Take the Dog for a Walk
8 p.m. to 9 p.m.
To you, walking the dog may be about exercise and, well, poop. To him, it’s all about the social life, explains Jean Donaldson, author of Dogs Are From Neptune (Lasar Multimedia, $17, www.amazon.com) and director of the San Francisco SPCA’s dog-training academy. Because owners have more time to stroll in the evening and to let their pets linger over exciting smells and sounds missed on the morning-rush walk, this is when Fido is happiest being out with pals.

The Best Time of Day to Exercise
5 p.m. to 6 p.m.
“For increasing fitness, decreasing the chance of injury, and improving sleep, the best time to exercise is late afternoon or early evening,” says Matthew Edlund, M.D., author of The Body Clock Advantage (Circadian Press, $15, www.amazon.com) and head of the Center for Circadian Medicine, in Sarasota, Florida. At these times, he says, your lungs use oxygen more efficiently, you’re more coordinated, and your muscles are warmed up, so you’re less likely to suffer a sprain or strain.

The Best Time of Day to Go to the Post Office
7:30 a.m. to 10 a.m.
The U.S. Postal Service may have more than 700,000 employees, yet there never seem to be enough of them when you’re waiting in line to mail that birthday present. Your best chance, according to USPS spokesperson Monica Suraci: Find out when your post office opens (generally between 7 a.m. and 9 a.m.) and arrive a half hour or so later. You’ll hit a midmorning lull, missing the rush of early birds lined up at the door (as well as distracted window personnel chatting with carriers sorting the day’s mail). Heavy traffic is more likely at lunch, at the end of the workday, and just before closing, so those are excellent times to avoid. Suraci’s tip: Look for USPS “contract stations,” which offer services in locations like supermarkets and drugstores, and for new machines being installed in some post-office lobbies that weigh and stamp packages most any time.

The Best Time of Day to Return Merchandise
10 a.m.
Arrive with your what-was-I-thinking sweater within the first hour a store is open. Workforces are leaner these days, but “retailers still need enough staff to open up, so that may be when they have the best ratio of staff to customers,” says Edward Fox, director of Southern Methodist University’s JCPenney Center for Retail Excellence, in Dallas. It may also be the only time all day when staff are at assigned posts, “so you can usually get someone to help,” notes former fashion stylist Linda Arroz, who spent years returning things she didn’t end up using for movies and TV shows. Fox adds that “the most experienced people get the best hours, so they” — not clueless newbies — “will be working the day shift.” Finally, consider customer flow. “A city store may be busier during weekday lunch hours, a suburban store on weekend afternoons,” says Target spokesperson Lena Michaud.

The Best Time of Day to Ask for a Raise
5 p.m.
"The key is finding a moment when your boss is not rushed and has time to truly listen," and that's most likely to be the end of the day, says Lynn Ellis, a career coach in Austin, Texas, who has worked with employees and bosses at global companies like Unilever. “That’s when I’m getting ready for the next day or looking ahead to the next week, and I’m in a good mood because I’m going home soon,” says Amy Holloway, a vice president at AngelouEconomics, in Austin. And you’ll have a biological edge then, since, as Body Clock Advantage (www.amazon.com) author Matthew Edlund, M.D., points out, your elevated body temperature makes you more alert in the late afternoon. But asking for a raise is not an exact science. Ellis advises tracking your boss’s daily habits to find the ideal, low-key time for him or her. And, in the end, if you’re at your best in the a.m., just go for it.

The Best Time of Day to Get a Haircut
8 a.m. to 9 a.m.
Booking the first appointment of the day will help you ease into the shampoo bowl on time. That’s because no latecomers will have thrown off the schedule, says Serena Chreky, co-owner of the Andre Chreky salon, in Washington, D.C. Saturday mornings (after busy workweeks or late Fridays) are usually the least frantic, says Allen Ruiz of the Jackson Ruiz Salon Spa, in Austin. However, some salons fill up then with bridal parties, Chreky cautions, so ask when you book. An early appointment may also get you the best cut. “Stress levels are at their lowest,” says Michelle Breyer, cofounder of NaturallyCurly.com, which deals with salons across the country. “Even if you’re only the third or fourth client of the day, your stylist may not look at your hair with the same enthusiasm.” For the very best service, Breyer and Ruiz both suggest asking your stylist, “What’s your favorite time of day to do hair?”

The Best Time of Day to Fly
Noon
Although U.S. Department of Transportation statistics show that flights taking off between 6 a.m. and 7 a.m. have the best on-time record (95.4 percent), those numbers are sometimes misleading, says Rally Caparas, an Atlanta-based air-traffic controller and a Travelocity "Eye on the Sky" correspondent for CNN. "On time" refers to when the plane pushes back from the gate. You can wait on the tarmac for an hour because of weather problems, which cause the vast majority of air delays. Scheduling arrivals and departures between 11 a.m. and 1 p.m. local time, Caparas says, will help you avoid most delay-causing weather patterns. This will also help you avoid airport rush hours, "which mostly coincide with workday rush hours," says Robert Baron, president of the Aviation Consulting Group, in Fort Lauderdale. But for best results, check your guidebook for regional weather patterns and schedule accordingly. For example, for the West Coast, fly in or out after noon Pacific Standard Time, when marine-level fog has dissipated, says Caparas. For southeastern and Gulf Coast hops, steer clear of the thunderstorms that kick up around 3 p.m. "Airline schedules are based on perfect weather conditions," he says. You're more likely to be punctual if you follow Mother Nature's schedule.

The Best Time of Day to Read (and Retain)
8 a.m. or 10 p.m.:
If you're going over notes for today's presentation or memorizing the names of your child's classmates' parents before the school open house tonight, do it early in the morning, when your immediate recall is highest. For longer retention (the book club meets in three weeks, but this weekend's your only chance to finish The Good Nanny), evening is better. "This is just the way the brain is organized," says Michael Smolensky, a professor of environmental physiology at the University of Texas School of Public Health at Houston and author of The Body Clock Guide to Better Health (Owl Books, $11, www.amazon.com). "Memory depends on nucleic acids, and those show circadian rhythms." In other words, your brain doesn't store information with the same efficiency all day; there are peaks and valleys. "College students often unknowingly take advantage of the dual circadian rhythm by staying up late studying, then doing a quick review the morning of the exam," says Smolensky.
