Reading a Calendar

By reading a calendar, you can know about the current year, month, and day. You can keep yourself aware of and prepared for future events and their respective dates accordingly. Thus, you can keep track of the days, weeks, months, and years.

Suppose you want to know the day on which Independence Day will fall in the year $2022$.

  • Open the calendar for the year $2022$.
  • Open the August page.
  • Mark August $15$.
  • Following the column upwards you can see that Independence Day is on Monday.

What is a Leap Year?

As mentioned above a leap year has $366$ days. What does a leap year mean? 

A leap year is a year when $1$ extra day, referred to as a leap day(February $29$) is added to the shortest month, February. It is done to keep our calendar in alignment with the Earth’s revolutions around the Sun. The Earth takes approximately $365.242189$ days which is equivalent to $365$ days, $5$ hours, $48$ minutes, and $45$ seconds – to complete one revolution around the Sun referred to as a tropical year.

A leap year has 366 days instead of the usual 365 days and occurs almost every four years.

Note:

The actual time Earth takes to complete one revolution = $365$ days, $5$ hours, $48$ minutes, and $45$ seconds

Number of days in a normal year = $365$ days

Extra time left = $5$ hours, $48$ minutes, and $45$ seconds = $0.242189$ days

Extra time accumulated in $4$ years = $0.242189 \times 4 = 0.968756 \approx1$ day

How To Check For a Leap Year?

To check for a leap year divide the year by $4$. If it is completely divisible by $4$, it is a leap year. For example, $2020$ is divisible by $4$, thus it is a leap year with a February of $29$ days.

But there is an exception to this rule and that is in a century year.

Century years like $600$, $900$, $1300$, $2000$, and many like these need to be divided by $400$ to check whether they are leap years or not. For example, a century year like $2000$ is divisible by $400$, so it is a leap year. However, a century year like $1300$ is not divisible by $400$, thus it is not a leap year, even though it is divisible by $4$.

Conclusion

A calendar is a chart or series of pages that shows the days, weeks, and months of a particular year. The complete year is divided into $12$ months and $52$ complete weeks, where a week is a period of $7$ days. A normal year has $365$ days whereas a leap year has $366$ days. Reading a calendar is one of the important skills one should have as it helps in time management.
