According to some intellectuals, we are already in the 21st century, and the 20th century was gone with 1900 century. But if we calculate the math, then this is the 20th century.

This century and decade names will help people to compare the previous situation and current situation. It is helpful in every field of this world; people look into history and measure whether they are moving forward or still backward. These words help people to manage the time and correctly calculate them.

How to Measure Decade or Century?

It is very technical mathematically, and here we are going to measure to understand it mathematically. Yes, you can take your calculator and check it out by yourself. Before we move forward to a decade or century, first, we need to know about a day, month, or a single year.

We all know that there are 365 days in a year, 30 days in April, June, September, and November. There are 31 days in January, March, May, July, August, October, and December, 28 Days in February, and after every 4 years, it has a leap year that has 29 days in February.

Let’s get more details

  • 1 minute = 60 seconds
  • 1 hour = 60 minutes
  • 60 minutes x 60 seconds = 3,600 seconds
  • 24 hours in a day
  • 24 hours x 60 minutes = 1440 minutes in a day
  • 1440 x 60 seconds = 86,400 seconds in a day.
  • 28 days for February months
  • 1 day = 1, 440 minutes
  • 1,440 minutes x 60 seconds = 86, 400 seconds in a day
  • 28 days x 1, 440 minutes = 40, 320 minutes in a month
  • 40, 320 minutes for the month of February x 60 seconds = 2, 419, 200 seconds for 28days

We can change a little bit when it comes to the leap year; the number will increase. Now let’s come to the months having 30 days for April, June, September, November.

  • 1 day = 1, 440 minutes
  • 1,440 minutes x 60 seconds = 86, 400 seconds in a day
  • 30 days x 1, 440 minutes =43, 200 minutes in a month
  • April, June, September, November = 120 days
  • 120 days x 1,440 minutes = 172, 800 minutes in 4 months
  • 43, 200 minutes in a month x 4 = 172, 800
  • 172, 800 minutes for 4 months x 60 seconds = 10, 368, 000 seconds for 120 days.

Now check out month of January, March, May, July, August, October, December

  • 1 day = 1, 440 minutes
  • 1,440 minutes x 60 seconds = 86, 400 seconds in a day
  • 31 days x 1,440 minutes = 44, 640 minutes in a month
  • January, March, May, July, August, October, December
  • 217 days x 1, 440 minutes = 312, 480 minutes in 7 months
  • 44,640 minutes in a month x 7 = 312, 480
  • 312, 480 minutes for 7 months x 60 seconds = 18, 748, 800 seconds for 217 days

Now short it to the year so it makes the understandable. In a Year there are 365 days

  • 365 days x 1440 minutes = 525, 600 minutes
  • 525, 600 minutes x 60 seconds = 31, 536, 000

Now imagine extending this math to a decade and a century, and the numbers will be unbelievable.
