A sun dial works by casting a shadow that is determined by the sun's position in the sky. Sun dials come in a variety of styles and shapes. Cheap, mass-produced sun dials often have design flaws that prevent them from accurately showing the time.
A:In a 24-hour day, a.m. and p.m. refer to the two 12-hour periods of the day. A.m. refers to the period between 12:00 in the morning and 11:59 in the late morning, whereas p.m. refers to the period between 12:00 midday and 11:59 in the late evening.
A:Military time is the representation of the time of the day as a 24-hour cycle, rather than the two 12-hour cycles more commonly used. The numbers for the a.m. cycle are identical to those of common time, but where common time specifies, for instance, 3 p.m. or 11 p.m, military time represents these as 1500 or 2300. Military times of 1300 or higher can be converted to common time simply by subtracting 1200.
A:A military time of 1730 equals 5:30 p.m. in standard time. Military time is a time format that utilizes a 24-hour time table and removes the a.m. and p.m. time designations. Military time is commonly known as 24-hour time.
A:The simplest way to convert civilian a.m./p.m. time to military time is to add 12 to every hour after 12 p.m. For example, 4 p.m. becomes 1600 hours. All a.m. hours are unchanged but have an "O" prefix and "hundred hour(s)" suffix instead of the typical "o'clock."
A:If a clock uses a standard seven-bar LED display, the most bars are lit at 12:08 and 8:08, which light 20 bars. Eight is the digit that lights up the most bars, illuminating all seven. Zero lights up six, while one and two account for seven bars together.
A:To use military time when figuring payroll, subtract each employee's check-in time from his check-out time. The answer is the total amount of hours that employee worked for the day. To convert regular time to military time, add 12 to any time after noon.
A:Analog and digital clocks work by using a power source to create regular vibrations. The vibrations are converted into electrical energy and then mechanical energy, which drives the gears and hands of the clock.
A:The time 12:00 noon, no matter the area on the Earth, is neither a.m. nor p.m. The same is true of 12:00 midnight, as it is neither a.m. nor p.m. as well. However, it is widely accepted that noon is considered p.m. and midnight is considered a.m. informally.
A:Atomic clocks work by exposing an atomic element to radio waves and then measuring the vibration between energy states of the atom's electrons. There are three main types of atomic clocks: cesium, rubidium and hydrogen. A second is defined as 9,192,631,770 cesium vibration cycles.
A:Official U.S. time from the Master Clock at the U.S. Naval Observatory is posted by zone on the Navy's time service website. This time is used by the Department of Defense and GPS Network. The exact time is also available at the National Institute of Standards and Technology website.
A:According to the Organization for Economic Co-Development, the average number of actual work hours in the United States, per worker per year was 1,790 in 2012. In 2000, the average was 1,836 for the United States.

A:Military time charts report time from 00:00 to 24:00 or from 0000 to 2400. Values less than 1200 are equivalent to the same civilian a.m. time. Military time values from 1200 to 2359 represent 12:00 p.m. to 11:59 p.m. civilian time.
A:The time 12 a.m. is also referred to as midnight, and 12 p.m. is referred to as noon. A good trick for remembering this is to think of 12:01 a.m. occurring during the night as well as the minute directly before it.
A:In the United States, daylight savings time (DST) commences on the second Sunday in March and ends the first Sunday in the month of November, states the Old Farmer's Almanac. On the specified date in March, the clocks are set 1 hour ahead at 2:00 a.m., and clocks are revert 1 hour back at the same time in November on the indicated day. However, DST in other countries can occur on different dates.
