Question

The calendar of the year 2020 can be used again in the year …………

Answer 1

Solution

To determine the next year when the calendar for 2020 can be reused, we need to consider the characteristics of the year:
Step 1. We knew that 2020 was a leap year.
2. A leap year must begin on the same day of the week the next time it has the same day-date combination.
2020 is a leap year, thus we must determine the following leap year that begins on the same day of the week. Leap years have a four-year cycle.
We know that 2020 was a leap year starting on Wednesday.
And The pattern for leap years and weekdays repeats every 28 years for leap years.
So, $2020 + 28$ = 2048.
So, 2020 calendar we can use in 2048.
Therefore, The correct option is (B).
