How do you calculate Greenwich hour angle?
The calculation is an hour for every 15 degrees you are away from the Greenwich meridian . You need to know your longitude , then do the calculation . Remember to do plus or minus depending if you are East or West....... eg. if you are in mid Atlantic somewhere , say 45 degrees West .....its minus three hours..
How many kilometer make 1 hour?
1hour = +-1665km if thats what you mean. its in the context of longitude... in the past when they wanted to know on which longitude someone was (on sea or ocean) they took the local time with them (pendulum clocks mostly) and they had a universal clock (by example moons of jupiter). so they could measure the difference of time from where they were and where they came from; once they knew the time difference they could know how far they went and on which longitude they were. Every longitude has the same time. there are 360 longitudes and +-24hours in a day. thats +-4minute for one longitude and One longitude is +- 111 km. So one hour is 60min and thats +-1665km. I hope this helped; if that was what you meant.
C program to find the angle between the needles of a clock?
minute_deg = minute * 360 / 60 = minute * 6;The hour hand will make a complete revolution every hour, so its formula is:hour_deg = hour * 360 / 12 = hour * 30;A function to find the angle would be:int angleBetweenHands(int hour, int minute){if(hour > 12) // In case of 24 hour clockhour -= 12;int angle = hour * 30 - minute * 6;if(angle > 180)angle = 360 - angle;return(angle);}Read more: C_code_to_find_angle_between_hour_hand_and_minute_hand
Name of imaginary line at which 24 hour day begins?
Greenwich meridian
Can you show a 130 angle?
Yes, I can.It is the angle between the hour hand and 12 when the time is 4:20Yes, I can.It is the angle between the hour hand and 12 when the time is 4:20Yes, I can.It is the angle between the hour hand and 12 when the time is 4:20Yes, I can.It is the angle between the hour hand and 12 when the time is 4:20
What is the longitude of a town if its local time is 6pm when greenwich time is 4pm?
The time difference between the local time and Greenwich Mean Time (GMT) is 2 hours. Since there are 360 degrees of longitude in a full circle and 24 hours in a day, each hour of time difference corresponds to 15 degrees of longitude. Therefore, the longitude of the town would be 30 degrees west of the Prime Meridian (Greenwich).

What is the hour and the date at 120 degrees east longitude?
England's Royal Observatory in Greenwich (the source of Greenwich Mean Time - GMT) is 0 degrees longitude and the reference point. 120 degrees East is the longitude of the east coast of Taiwan. At that longitude, 1/3 of a circumference from Greenwich, the standard time (and date) should be 8 hours ahead of Greenwich. So if it is 4am in Greenwich, it should be noon in Taiwan.
Which cities are ahead and before Greenwich time?
Typically countries in the western hemisphere with negative longitude values will be behind Greenwich time and those in the eastern hemisphere with positive longitude values will be ahead of Greenwich time. For example, Oslo Norway which is east of Greenwich is one hour ahead of GMT (GMT +1) and the Azores (GMT -1) which is west of Greenwich is one hour behind GMT.
What will be the time at 30 degree east of Greenwich if it is 12 noon at Greenwich?
If it is 12 noon at Greenwich (0 degrees longitude), then every 15 degrees of longitude corresponds to a one-hour time difference. Therefore, if you are 30 degrees east of Greenwich, the time would be 2:00 PM.
What is Hour angle system?
The hour angle system is a method used to measure the position of a celestial object in the sky. It measures the angular distance of an object from the observer's meridian, usually in hours (equivalent to 15 degrees per hour). By knowing the hour angle, one can determine the right ascension and declination of the object.
Why do you have timezone?
The Greenwich Meridian, also known as the prime meridian or International Meridian, is the "starting point" for dividing the Earth's surface into time zones. Each time zone is 15 degrees of longitude wide (with local variations) and the local time is one hour earlier than the zone immediately to the east on the map.
How does GMT differ from local time?
GMT stands for Greenwich Mean Time and it is the time in London or Lisbon. Local time is the time in your current location. Therefore, if you live in Rome, which is GMT+1, the time will be one hour later than the time in London (Greenwich). In the differnet time zones, one hour is added from Greenwich all the way round the world until you get back.
What is the purpose of time-zone?
The Greenwich Meridian, also known as the prime meridian or International Meridian, is the "starting point" for dividing the Earth's surface into time zones. Each time zone is 15 degrees of longitude wide (with local variations) and the local time is one hour earlier than the zone immediately to the east on the map
What is the time difference between two meridian lines?
The Greenwich Meridian, also known as the prime meridian or International Meridian, bisects the primary division of time zones. Each time zone is 15 degrees of longitude in width, with local variations, and observes a clock time one hour earlier than the zone immediately to the east. The time difference between two meridian lines is one hour (the time difference between two longitudinal lines is 4 minutes and consequently the time difference between 15 longitudinal lines; or two meridian lines; would be one hour). Refer to link below.The Greenwich Meridian bisects the primary division of time zones. Each time zone is 15 degrees of longitude in width, with local variations, and observes a clock time one hour earlier than the zone immediately to the east. The time difference between two meridian lines depends on where you draw the lines. There is no official standard set of lines that everyone is required to use, and a line can be drawn at ANY longitude. Whatever the longitude difference is between the two meridians you decide to consider, the time difference between them (in hours) is nominally 1/15 of that angle.
Why is Nigeria one hour ahead of Ghana?
Nigeria is one hour ahead of Ghana due their different position from the Greenwich meridian. Ghana is at the Greenwich meridian while Nigeria is at +1 Greenwich which accounts for the difference in one hour.
How does latitude and time relate?
They don't. Local time alters with longitude, by one hour per 15 degrees.
