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..

What is the obtuse angle of 4 o'clock?
To find the obtuse angle at 4 o'clock, we first calculate the angle between the hour and minute hands. The hour hand at 4 points to 120 degrees (4 hours × 30 degrees per hour), and the minute hand at 0 minutes points to 0 degrees. The angle between them is 120 degrees, and the obtuse angle is the larger angle, which is 360 degrees - 120 degrees, resulting in an obtuse angle of 240 degrees.
What is the smaller angle between 4 and 8 on a clock?
To find the smaller angle between the hour hand at 4 and the hour hand at 8 on a clock, we first calculate the angle for each hour mark. Each hour mark represents 30 degrees (360 degrees/12 hours). The angle between 4 and 8 is 4 hours apart, which is 4 × 30 = 120 degrees. Therefore, the smaller angle between 4 and 8 on a clock is 120 degrees.
What is the angle of 8.45 clock?
To calculate the angle of the clock hands at 8:45, we can use the formula for the angle between the hour and minute hands: Angle = |(30*hour - (11/2)minutes)|. Here, the hour is 8 and the minutes are 45. Plugging in the values gives us |(308 - (11/2)*45)| = |240 - 247.5| = | -7.5 | = 7.5 degrees. Therefore, the angle between the clock hands at 8:45 is 7.5 degrees.
What is the angle of rotation for the clock?
The angle of rotation for a clock's hour hand is 30 degrees for each hour, as it completes a full 360-degree rotation in 12 hours. For the minute hand, it moves 6 degrees for each minute, completing a full rotation in 60 minutes. To calculate the angle at a specific time, you can use these values based on the current hour and minute.
If the Greenwich Hour Angle (GHA) of the sun is 173 and deg and the Local Hour Angle (LHA) is 358 and deg ... What is the longitude?
To find the longitude, you can use the formula: Longitude = GHA - LHA. In this case, Longitude = 173° - 358° = -185°. Since longitude values range from -180° to 180°, you can add 360° to get a positive value: -185° + 360° = 175°. Thus, the longitude is 175° East.
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 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.
What is the time 20 degree west when it is 12 noon at greenwich?
When it is 12 noon at Greenwich (0 degrees longitude), it is 20 degrees west of Greenwich. Since the Earth rotates at 15 degrees per hour, you can calculate the time difference by dividing 20 degrees by 15, which equals approximately 1 hour and 20 minutes. Therefore, it would be 10:40 AM at the location that is 20 degrees west when it is 12 noon at Greenwich.
How long from Heathrow to greenwich?
About 1 hour
What is the time difference of Amsterdam Holland and Rome Italy?
Holland is (Greenwich Mean Time) GMT +1 hour, ie. 1 hour ahead of Greenwich, England. Italy is (Greenwich Mean Time) GMT +1 hour, ie. 1 hour ahead of Greenwich, England. There is no time difference between Amsterdam and Rome. (Daylight savings not taken into account.)
How do you calculate from GMT?
If you are to the west of the Greenwich Meridian (as is the US, for example) You subtract an hour for each time zone. Eastern Standard Time in the US is 5 hours behind GMT. Be sure to adjust for daylight saving time. GMT is always standard time. If you are to the east of the Greenwich Meridian, you add an hour for each time zone.
What is the obtuse angle of 4 o'clock?
To find the obtuse angle at 4 o'clock, we first calculate the angle between the hour and minute hands. The hour hand at 4 points to 120 degrees (4 hours × 30 degrees per hour), and the minute hand at 0 minutes points to 0 degrees. The angle between them is 120 degrees, and the obtuse angle is the larger angle, which is 360 degrees - 120 degrees, resulting in an obtuse angle of 240 degrees.
What is the time difference between Germany and California?
California is (Greenwich Mean Time) GMT -8 hours, ie. 8 hours behind Greenwich, England. Germany is (Greenwich Mean Time) GMT +1 hour, ie. 1 hour ahead of Greenwich, England. California is 9 hours behind Germany. (Daylight savings not taken into account.)
What is the smaller angle between 4 and 8 on a clock?
To find the smaller angle between the hour hand at 4 and the hour hand at 8 on a clock, we first calculate the angle for each hour mark. Each hour mark represents 30 degrees (360 degrees/12 hours). The angle between 4 and 8 is 4 hours apart, which is 4 × 30 = 120 degrees. Therefore, the smaller angle between 4 and 8 on a clock is 120 degrees.
What is the time difference between England and Munich?
England is at (Greenwich Mean Time) GMT. Munich is (Greenwich Mean Time) GMT +1 hour, ie. 1 hour ahead of Greenwich, England. England is 1 hour behind Munich. (Daylight savings not taken into account.)
What is the angle of 8.45 clock?

Here, the hour is 8 and the minutes are 45. Plugging in the values gives us |(308 - (11/2)*45)| = |240 - 247.5| = | -7.5 | = 7.5 degrees. Therefore, the angle between the clock hands at 8:45 is 7.5 degrees.
How do you calculate the angle of a right angle?
The definition of a right angle is an angle measuring 90 degrees. You don't have to calculate anything.
