The calendar of the year 1992 can be used again in the year?a)2010b)20...
Explanation:
The year 1992 was a leap year, which means it had one extra day compared to a regular year. A leap year occurs every four years to account for the fact that the Earth's orbit around the sun takes approximately 365.25 days.
To determine if the calendar of 1992 can be used again in a future year, we need to consider the following factors:
1. Leap Year Cycle:
The leap year cycle repeats every four years. This means that the calendar of 1992 can be used again in any year that is a multiple of four years after 1992.
2. Year Adjustment:
To account for the slight discrepancy between the actual solar year and the calendar year, a small adjustment is made. This adjustment involves skipping leap years in years divisible by 100, except for those divisible by 400. For example, the year 1900 was not a leap year, even though it was divisible by four, because it is divisible by 100 but not by 400.
Based on these factors, we can determine that the calendar of 1992 can be used again in the following years:
- 1996: The next leap year after 1992.
- 2000: A leap year divisible by 400, so the adjustment rule does not apply.
- 2004, 2008, 2012, 2016: Leap years divisible by four.
- 2020: The next leap year after 2016.
Therefore, the correct answer is option B (2020), as the calendar of 1992 can be used again in that year.
