Though Calculations are part and partial of our daily lives most of us always tend to boycott them, forgetting that almost all we do involves calculations, take an instance of your daily routine; do you ever count the number of times you breathe in a day?

Do you ever count all the steps you take? Do you count the number of times you blink in an entire day? Well, there is no way you can escape mathematics even if you pretend it never exists.

Similarly, in scientific mathematics, we encounter multiple measurements and these are not just pure numbers.

The figures given are usually a representation of physical quantities such as; time, length and mass and these depend on their different units of measurements.

The standard unit of measuring time are seconds (s).

Years contain about 57 weeks, each week is made up of 7 days, each day contains 24 hours, each hour contains 60 minutes and each minute contains 60 seconds. Given that sequence, the question of “how many minutes are in a year” seems so simple but thousands of people could actually fail it.

## How Many Minutes Are in a Year?

Years begin and end sooner than we least expect and the truth is most of us tend to go through them only acknowledging that they either have 365 or 366 days forgetting that the tiny microsecond accounts for the 366 days.

**The number of minutes in a year varies according to the number of days in a year. The Gregorian estimate of 365.2425 days in a year, 365 days in a normal year and 366 days in a leap year are all considered. Below is a compilation of the number of minutes in the different years; –**

### Minutes in a Gregorian year

An average Gregorian year has 365.2425 days.

This implies that;-

- a) The number of weeks in a Gregorian year are (365.2425 ÷ 7 days that make a week)

= 52.1775 weeks

- b) The number of hours in each Gregorian year are (365.2425 × 24)

= 8765.82 hours

Hence the number of minutes in a Gregorian year are (8765.82) × 60 minutes

= __525,949.2 minutes __

### Minutes in a common year

According to the calendar, a normal/common year has 365 days. The number of weeks in a common year are therefore = (365 ÷ 7) = 52.143 weeks

The number of hours in normal year are (365 × 24) = 8760 hours. The 8760 hours are equal to (8760× 60 minutes in each hour) = **525600 minutes in a normal year.**

### The number of minutes in a leap year

In a leap year, there are 366 days. This equals to (366×24 hours in each day) making a total of 8,784 hours in the whole year. The number of minutes in a leap year are therefore (8,784 × 60) = **527,040 minutes in a leap year**

### Who Invented Time?

The phrase “inventing time” sounds impossible or rather peculiar, some people actually think time was not invented but rather it has existed “since the beginning of time”.

Even so, the Egyptians and Babylonians are believed to have started measuring time approximately 5,000 years ago and this is confirmed by archeological findings.

### How Hours Were Counted in the Early Years

Hipparchus who worked basically between 147B.C to 127B.C suggested that a day should be divided into 24 equinoctial hours considering 12 daylight hours and 12 night hours observed during the equinox days.

### How was time measured in the ancient days?

Egyptians used analogue devices referred to as sundials, these were originally created by the Babylonians in Babylon more than 6,000 years earlier.

The sundials were developed into a more functional state in ancient Egypt and they were continuously used even thousands of years later.

Sandials are analogue instruments that show time by the shadow of a pointer cast by the sun onto a plate marked by hours of the day.

As the day matures, the sun moves across the sky from the east to the west; the sun’s motion causes the shadow of the sundial pointer to gradually change position hence indicating the passage of time this could have been technically referred to as an ancient clock.

### Who came up with the 60seconds in an hour and how?

Around 2000Bc, the Babylonians made astronomical calculations in base 60 (**hexadecimal)** that they adopted from the **Sumerians **who are believed to have been their ancestors.

The number 60 is believed to have been used because of its convenience when dealing with fractions.

Bashing on this, the early Sumerians were able to divide day and night in 12 hour intervals/ periods.

The Sumerians further divided each hour into 60 minutes and each minute into 60 seconds.

### The Pendulum Clocks

In the early 1656, Christiaan Huygens developed and patented the very first pendulum clock and most people found them useful. The first pendulum clocks were quickly refined in order to boost on the precision

### The Mechanical Clocks and the Second Displaying Clocks.

As the sexagesimal divisions of time became more established in Europe, mechanical clocks were adopted and these kept mean time as opposed to the apparent time displayed by the sundials.

In the last half of the sixteenth century, the first clocks that displayed seconds were introduced and as of 1787, Levi Hutchins and American from New Hampshire invented a mechanical Alarm clock. In 1876, Hutchins alarm clock was improved to a settable alarm clock.

## Conclusion

The concept of time was initially introduced by the ancient Biblically known Sumerians. This group of people were so innovative and are actually responsible for having introduced the first schools, government bureaucracy, some Old Testament stories in the bible, heroin epics and do many other things which we tend to boycott in the presentation day.

The number of minutes in a year is greatly determined by the number of days a year has and therefore ranges depending depending on whether it is a leap year or not.
