Why Clock rotates clockwise direction?
The direction in which clocks are designed to move was likely influenced by sundials, which tracked the movement of the sun's shadows in the Northern Hemisphere. The clockwise direction was chosen for consistency and ease of reading, as it matched the natural movement of shadow on a sundial. Over time, this convention became standardized in clock design.
How long is 599 seconds in hours?
1h=60min 1min=60s 599s/(60s/min)=9.98min (or 9min 59s) 9.98min/(60min/h)=0.166333333h
Why there is no year zero in our calendar?
Our system of numbering the year originated from the birth of Jesus Christ (hence the terms BC - Before Christ and AD - Anno Domini - in the year of Our Lord). This system did not become widespread for many years after Jesus ans so the years had to be counted back to when iit was believed he was born. However, there were two mistakes in the calculation; first, there was no year zero included (so the year before 1 AD was 1 BC) and, in any case, the year which they took to be Christ's birth was also wrong, his actually being born in or around what we call 4 BC. But the calendar, with its errors, stuck - and we have been using it ever since over 2000 years later.
How many hours are there in seven days?
It depends upon the what a day is being measured as. The most basic way to solve this question: One day is the equivalent to 24 hours, so to find the amount of hours in seven days, then multiply 24 by 7, which is 168 hours.
However, if we use sidereal day (a day measured with respect to the stars), then a day equivalent to 23 hours, 56 minutes, and 4 seconds, or 23.934444... after converting into a decimal. Multiplying this number by 7 days would yield the answer of 167.54111 hours.
How do you convert 525600 minutes to days?
A minute equals 0.000694444444 days, or 6.94444444 x 10-4 days. To convert minutes to days, just multiply your minutes by 6.94444444 x 10-4. It turns out that it's right at about 365 days. And 365 days happens to be a year, as you might have seen.
With a "regular" alarm clock, your alarm would go off at nine p.m. and you'd be stuck resetting it to have it go off at nine a.m. You may get 1 + 12 or 13 hours of sleep. Maybe. If you had a contemporary electric (electronic) alarm clock, it could be set for nine p.m. or nine a.m. You'd get 13 hours of sleep without being awakened one hour after setting the alarm. Some of us have been around for a while and used both kinds of clock, and the "original" alarm clocks were around before the snazzy new fangled ones. And we know the drill.
What is the time difference between England and the Bahamas?
England is usually five hours ahead of the Bahamas, except for the two or three weeks between the second and last Sundays of March and the week between the last Sunday of October and the first Sunday of November, when the time difference is four hours.
Mar-Oct: When it's 8 AM EDT in the Bahamas, it's 1 PM BST in England.
Oct-Nov: When it's 8 AM EDT in the Bahamas, it's 12 noon GMT in England.
Nov-Mar: When it's 7 AM EST in the Bahamas, it's 12 noon GMT in England.
Mar: When it's 8 AM EDT in the Bahamas, it's 12 noon GMT in England.
EST = Eastern Standard Time = UTC-5
EDT = Eastern Daylight Saving Time = UTC-4
GMT = Greenwich Mean Time = UTC
BST = British Summer Time = UTC+1
How many days are there in a week?
There are 7 days in a week. The 7 days are Monday, Tuesday, Wednesday, Thursday, Friday, Saturday and Sunday.
How many minutes are there in four years?
525600 minutes in one year. You do the math. Multiply by 4.
How many hours in 400 minutes?
WHEN TRYING TO FIND OUT HOURS, YOU DIVIDE BY NUMBER OF MINUTES BY 60. SO 400 MINUTES EQUALS 6 HOURS AND 40 MINUTES
Who decided how much time equals a second a minute an hour?
Although history never defined a singular person, it is widely believed the Babylonians divided time into increments using a base system of 60, creating the basis for modern time as well still know it.
------- The Egyptians had subdivided daytime and nighttime into twelve hours each since at least 2000 BC, hence their hours varied seasonally. The Hellenistic astronomers Hipparchus (c. 150 BC) and Ptolemy (c. AD 150) subdivided the day sexagesimally and also used a mean hour (1/24 day), but did not use distinctly named smaller units of time. Instead they used simple fractions of an hour.
The day was subdivided sexagesimally, that is by 1/60, by 1/60 of that, by 1/60 of that, etc., to at least six places after the sexagesimal point (a precision of less than 2 microseconds) by the Babylonians after 300 BC, but they did not sexagesimally subdivide smaller units of time. For example, six fractional sexagesimal places of a day was used in their specification of the length of the year, although they were unable to measure such a small fraction of a day in real time. As another example, they specified that the mean synodic month was 29;31,50,8,20 days (four fractional sexagesimal positions), which was repeated by Hipparchus and Ptolemy sexagesimally, and is currently the mean synodic month of the Hebrew calendar, though restated as 29 days 12 hours 793 halakim (where 1 hour = 1080 halakim). The Babylonians did not use the hour, but did use a double-hour, a time-degree lasting four of our minutes, and a barleycorn lasting 3? of our seconds (the helek of the modern Hebrew calendar).
In 1000, the Muslim scholar al-Biruni gave the times of the new moons of specific weeks as a number of days, hours, minutes, seconds, thirds, and fourths after noon Sunday. In 1267, the medieval scientist Roger Bacon stated the times of full moons as a number of hours, minutes, seconds, thirds, and fourths (horae, minuta, secunda, tertia, and quarta) after noon on specified calendar dates. Although a third for 1/60 of a second remains in some languages, for example Polish (tercja) and Arabic (?????), the modern second is subdivided decimally.
The first attempt at creating a clock that could measure time in seconds was created by Taqi al-Din at the Istanbul observatory of al-Din between 1577-1580. He called it the "observational clock" in his In the Nabik Tree of the Extremity of Thoughts, where he described it as "a mechanical clock with three dials which show the hours, the minutes, and the seconds." He used it as an astronomical clock, particularly for measuring the right ascension of the stars.

What are the benefits of time management?
Your life will be calmer and more enjoyable. In business it identifies productive behaviour and can help with making profits.
72 hours are how many days in a week?
There are 24 hours in one day. 24 x 3 = 72 That equals three days. One day is 24 hours, so 72 hours is three days.
