The word horologia (from the Greek ὥρα, hour, and λέγειν, to tell) was used to describe early mechanical clocks,[15] but the use of this word (still used in several Romance languages) [16] for all timekeepers conceals the true nature of the mechanisms. For example, there is a record that in 1176 Sens Cathedral installed a ‘horologe’[17] but the mechanism used is unknown. According to Jocelin of Brakelond, in 1198 during a fire at the abbey of St Edmundsbury (now Bury St Edmunds), the monks 'ran to the clock' to fetch water, indicating that their water clock had a reservoir large enough to help extinguish the occasional fire.[18] The word clock (from the Celtic words clocca and clogan, both meaning "bell"), which gradually supersedes "horologe", suggests that it was the sound of bells which also characterized the prototype mechanical clocks that appeared during the 13th century in Europe.
“This was a gift for my elderly, cognitively impaired mother. She was very often confused as to which day it was, the time of day, etc. She would show up at appointments on the wrong day, or think it was morning when it was evening. This clock is fantastic! It has made such a difference. Now she always knows what day and time it is. The clock is also very nice-looking. This was an excellent purchase and highly recommended. I can’t say enough good things about it.”

By the time that phone hits the nightstand, you've lost precious sleep time, you've tricked your brain into thinking it's wake-up time instead of dream time, because the glow of the blue light emitted by your phone reduces your body's release of melatonin, the hormone that regulates your sleep cycle. Instead of relaxing, you've stimulated your mind. All of that adds up to poor quality sleep followed by a groggy, foggy, "I don't know why I'm so tired," kind of morning.

In addition to radio, recent clock radios have other music sources such as iPod, iPhone, and/or audio CD. When the alarm is triggered, it can play a set radio station or the music from a selected music source to awaken the sleeper. These models usually come with a dock for iPod/iPhone that also charges the device while it is docked. They can play FM/AM radio, iPod/iPhone or CD like a typical music player as well (without being triggered by the alarm function). A few popular models offer "nature sounds" like rain, forest, fire, sea, waterfall etc., in place of the buzzer.

Replaced Old English dægmæl, from dæg "day" + mæl "measure, mark" (see meal (n.1)). The Latin word was horologium; the Greeks used a water-clock (klepsydra, literally "water thief"). Image of put (or set) the clock back "return to an earlier state or system" is from 1862. Round-the-clock (adj.) is from 1943, originally in reference to bomber air raids.
Go to bed with positive thoughts. Tell yourself, “I want to get up early because…” and then, actually do it. Sleep studies happen all the time, and they tell us what exterior activities are affecting our dreams, our nightmares, etc., and talking to yourself as you drift off to bed has been proven to work. If you’re looking forward to something in the morning, tell yourself about it, and your body will hold onto that through the night.

In a clock driven by a weight or a spring, the power is first transmitted by the main, or great, wheel. This engages with a pinion (a gear with a small number of teeth designed to mesh with a larger wheel), whose arbor (a turning rod to which gears are attached) is attached to the second wheel that, in its turn, engages with the next pinion, and so on, down through the train to the escapement. The gear ratios are such that one arbor, usually the second or third, rotates once an hour and can be used to carry the minute hand. A simple 12-to-1 gearing, known as the motion work, gives the necessary step-down ratio to drive the hour hand. The spring or weight is fitted with a mechanism so it can be rewound when necessary, and the arbor carrying the minute hand is provided with a simple slipping clutch that allows the hands to be set to the correct time.
Waking up might be a little bit more pleasant when you can choose between a buzzer, the radio, or your favorite songs streaming from your smartphone or MP3 player to nudge you out of dreamland. Add to that the fun of seeing the time of day (or night) projected in large, red numerals onto your ceiling — you don't even have to turn your head to figure out how much more sleep you'll get if you can just fall back into slumber right now — and the large LCD display on the clock's face, and you have just some of the features that make the Electrohome Projection Alarm Clock our top pick.
"Stripe Clock" is a modern metallic design created by the artist, Belle. Measured at 24 inches on each side, this metal art is made from a single sheet of metal expertly grinded and tinted and made in to a functional clock. It is mainly characterized by the bright stripe in the middle of the sheet of metal. Each stroke and grind pattern on this piece accentuates the beauty of the plain sheet of metal. The glimmer coming from the shallow grinds are like street lights illuminating the city in the...
Special features beyond simply keeping time can be either practical or decorative. Often found in the kitchen or other busy room, some digital clocks can show readings of the indoor or outdoor temperature, display the date, and have the capacity to set an alarm or timer. A swinging pendulum is most commonly found on fancier wood and metal clocks, though some novelty styles also feature a pendulum.
Synchronous electric clocks do not have an internal oscillator, but count cycles of the 50 or 60 Hz oscillation of the AC power line, which is synchronized by the utility to a precision oscillator. The counting may be done electronically, usually in clocks with digital displays, or, in analog clocks, the AC may drive a synchronous motor which rotates an exact fraction of a revolution for every cycle of the line voltage, and drives the gear train. Although changes in the grid line frequency due to load variations may cause the clock to temporarily gain or lose several seconds during the course of a day, the total number of cycles per 24 hours is maintained extremely accurately by the utility company, so that the clock keeps time accurately over long periods.

late 14c., clokke, originally "clock with bells," probably from Middle Dutch clocke (Dutch klok) "a clock," from Old North French cloque (Old French cloke, Modern French cloche), from Medieval Latin (7c.) clocca "bell," probably from Celtic (cf. Old Irish clocc, Welsh cloch, Manx clagg "a bell") and spread by Irish missionaries (unless the Celtic words are from Latin); ultimately of imitative origin.
In mechanical clocks, the low Q of the balance wheel or pendulum oscillator made them very sensitive to the disturbing effect of the impulses of the escapement, so the escapement had a great effect on the accuracy of the clock, and many escapement designs were tried. The higher Q of resonators in electronic clocks makes them relatively insensitive to the disturbing effects of the drive power, so the driving oscillator circuit is a much less critical component.[2]

Early clock dials did not indicate minutes and seconds. A clock with a dial indicating minutes was illustrated in a 1475 manuscript by Paulus Almanus,[31] and some 15th-century clocks in Germany indicated minutes and seconds.[32] An early record of a seconds hand on a clock dates back to about 1560 on a clock now in the Fremersdorf collection.[33]:417–418[34]

In 1283, a large clock was installed at Dunstable Priory; its location above the rood screen suggests that it was not a water clock.[citation needed] In 1292, Canterbury Cathedral installed a 'great horloge'. Over the next 30 years there are mentions of clocks at a number of ecclesiastical institutions in England, Italy, and France. In 1322, a new clock was installed in Norwich, an expensive replacement for an earlier clock installed in 1273. This had a large (2 metre) astronomical dial with automata and bells. The costs of the installation included the full-time employment of two clockkeepers for two years.[citation needed]
If you've moved away from using a clock completely and instead set an alarm on your phone, consider the SmartShaker by iLuv. The device slides under your pillow and shakes you awake when your phone alarm goes off (it connects wirelessly using bluetooth). You can also have the device sound an audible alarm. The battery lasts a full month before needing to be charged.

For example, there is a record that in 1176 Sens Cathedral installed a ‘horologe’[17] but the mechanism used is unknown.

The Electrohome Projection Alarm Clock is the second-best selling alarm clock on Amazon, with more than 9,700 reviews. Many buyers praised the projection feature, and particularly liked the fact that the brightness of the blue LCD display can be adjusted; for some owners, the clock's light is just a little too intense. The ability to set one alarm time for Monday through Friday, and a separate time for the weekend was another popular feature.
In a master clock system, electricity is used to give direct impulses to the pendulum, which in turn causes the clock’s gear train to move, or to lift a lever after it has imparted an impulse to the pendulum. In various modern master clocks the pendulum operates a light count wheel that turns through the pitch of one tooth every double swing and is arranged to release a lever every half minute. This lever gives an impulse to the pendulum and is then restored to its original position by an electromagnet. The pulse of current that operates the electromagnet can also be transmitted to a series of distant dials, or slave clocks, advancing the hands of each through the space of a half minute. Thus, a master clock can control scores of dials in a large group of buildings, as well as such other apparatus as time recorders and sirens.
Certainly not just for telling time, this oversized wall clock makes a statement whether set in the entryway or above your living room mantel. Its frame is crafted from metal with an antiqued silver leaf design for metallic allure. The openwork design allows it to seamlessly blend with your ensemble, while a fun analog dial lends a pop of playful appeal. Requires one AA battery to operate.
Small in size but striking in style, this eye-catching wall clock brings a dash of contemporary flair to any arrangement in your home. Showcasing a sunburst silhouette measuring 20" in diameter, this round silver-finished design is crafted with an iron and mirrored frame comprised of black spokes with orb-like accents. A petite glass clock face with sword-style hands sits in the center, allowing you to keep an eye on the hour in any room.
Electric currents can be used to replace the weight or spring as a source of power and as a means of signaling time indications from a central master clock to a wide range of distant indicating dials. Invented in 1840, the first battery electric clock was driven by a spring and pendulum and employed an electrical impulse to operate a number of dials. Considerable experimental work followed, and it was not until 1906 that the first self-contained battery-driven clock was invented.

The pendulum is a reliable time measurer because, for small arcs, the time required for a complete swing (period) depends only on the length of the pendulum and is almost independent of the extent of the arc. The length of a pendulum with a period of one second is about 39 inches (990 mm), and an increase in length of 0.001 inch (0.025 mm) will make the clock lose about one second per day. Altering the length of a pendulum is therefore a sensitive means of regulation. The alteration is usually carried out by allowing the bob to rest upon a nut that can be screwed up or down the pendulum rod.
In the modern day and age, clocks are everywhere, from your phone to your computer or even on your wrist as a fashion item. A modern clock can be used for more than just telling time, a wall clock makes for a great design piece for your home. There are contrasting types of clocks ranging from analog to oversized, and they come in an assortment of shapes and material as well. Clocks are interesting wall decorations because they are constantly looked at to figure out the time, which makes finding a wall clock that fits your style that much more important.
Traditional mechanical alarm clocks have one or two bells that ring by means of a mainspring that powers a gear to propel a hammer back and forth between the two bells or between the interior sides of a single bell. In some models, the back encasement of the clock itself acts as the bell. In an electric bell-style alarm clock, the bell is rung by an electromagnetic circuit and armature that turns the circuit on and off repeatedly.[1]
Another type of analog clock is the sundial, which tracks the sun continuously, registering the time by the shadow position of its gnomon. Because the sun does not adjust to daylight saving time, users must add an hour during that time. Corrections must also be made for the equation of time, and for the difference between the longitudes of the sundial and of the central meridian of the time zone that is being used (i.e. 15 degrees east of the prime meridian for each hour that the time zone is ahead of GMT). Sundials use some or part of the 24 hour analog dial. There also exist clocks which use a digital display despite having an analog mechanism—these are commonly referred to as flip clocks. Alternative systems have been proposed. For example, the "Twelv" clock indicates the current hour using one of twelve colors, and indicates the minute by showing a proportion of a circular disk, similar to a moon phase.[74]
