Interchange of Hands Clocks

The interchange of the hands of the clock is referred to as the swap of the second, minute, as well as the hour hand with each other.

In order to analyze the interchangeable characteristics of the second, minute, as well as the hour hands of the clock, an inspection of the time frame is needed to be executed. The location of the three hands is an indicator of the interchange occurring among them. In the course of identifying the occurrence of the inter swap among the hands of the clock, the distance between the hands from the dials of the clock is a significant factor to be noticed. An observation made after one hour is regarded as a key to find out the interchanging time among the hands.

What are Clocks and Calendars?

A “clock” is an electrical or mechanical instrument that is identified as a replacement of the watches in order to measure the time with the help of the indications made by the hands of the clock. There are three hands present in the clock namely the “second hand”, the “minute hand”, as well as the “hour hand”. The “second hand” is viewed as an indicator of the seconds of the time frame. On the other hand, the “minute hand” is known for indicating the quantification of the minutes of the time frame. In the same way, the “hour hand” is observed in order to get an idea of the measurement of the hours within the time frame.

A “calendar” is referred to as a series or chart that is utilized in order to note the passage of the “days”, “weeks”, “months”, as well as “year” by means of the “dates”. In other words, the calendar is regarded as a device that is used in order to keep records of the whole year in a systematic manner. A calendar is used in every sector of the society in order to maintain the working schedule along with finishing the tasks before deadlines. The “calendar” is also referred to as a “solar dating system” that helps in following the time frame with the same pace all over the world and hence is adopted as a universal dating tool.

Deliberation on Interchange of Hands of the Clocks

In the course of finding out the duration when the hands of the clocks interchange their locations or positions, there is a need for the observer to analyze the point at which the minute, as well as the hour hand collide, as well as cross each other to interchange each other’s initial positions. This is done by keeping the record of the movements of both the clock hands throughout the time frame of 12 hours, and observation is recorded after the compilation of each hour within the time frame. Moreover, the interchange of the hands of the clock is found to be helpful in analyzing the time determination within the time frame of 12 hours.

Background of clock hands exchange

The hands of the clocks always maintain their characteristic of rotating around the clock dial “in the clockwise direction”, that is in the “direction of ascending numbers”. The “second hand” is found to move the fastest. On the other hand, the “minute hand” moves comparatively slower than the “second hand”, and the “hour hand” moves the slowest. The rotation of the hands is completed every 12 hours of the rotation. During this time frame, the hands exchange their positions from time to time which are identified by the record of their collision within the 12 hours. The rotation depicts the continuity of the time frame throughout the world without any barrier. This means that time is irreversible and never stops moving irrespective of any barrier. The clock hand exchange is analyzed at the global level in order to furnish the target jobs within the required time frame. 

How many times do the hands of the clocks collide?

The clock hands are found to collide with each other once every one hour within the time frame. This means that within 12 hours, the clock hands meet with each other 11 times. This is found to occur as a result of one collision between 12 o’clock, as well as 1 o’clock. Both the clock hands are found to either remain in the “same straight line” at the time of collision between them, or persist “opposite to each other”. In the case of the clock hands maintaining a right angled position, there is a space gap of 15 minutes between the clock hands. On the other hand, it is identified that in the case of the clock hands facing opposite directions, there is a space gap of 30 minutes between them. Moreover, both the clock hands are found to collide after a duration of 65 minutes whenever the movements of the clock hands are maintained at normal speeds.


On the basis of the study, it is concluded that both the clock, as well as the calendar are considered to be vital devices that are given the same level of importance throughout the world. These devices are taken into consideration in order to follow a disciplined schedule of the day to day life in a systematic way. Since time is considered to be an eternal factor, the clocks and calendars act as significant factors in maintaining the decorum of the daily routine across the world.
