Leap Year Adjustments and Discrepancies

The video explains the concept of a leap year, which occurs every four years to account for the extra 5.8 hours Earth takes to orbit the Sun beyond 365 days. Without leap years, our calendar would be misaligned by 24 days in 100 years. The video details the calculation and rules for leap years, including skipping a leap year at the start of a century unless divisible by 400. This adjustment ensures our calendar remains accurate over millennia.

Why do we add an extra day to the calendar in a leap year?

• To align with the lunar calendar

• To make February longer

• To correct the calendar year with Earth's orbit

• To celebrate a special holiday

How long does it actually take for Earth to complete one revolution around the Sun?

• 365 days

• 364 days

• 365 days and some change

• 366 days

What is the discrepancy in hours each year if we don't add a leap day?

• 3.9 extra hours

• 6.2 extra hours

• 4.5 extra hours

• 5.8 extra hours

What is the solution to the yearly discrepancy in the calendar?

• Add a day every year

• Add a week every century

• Add a day every four years

• Remove a day every four years

What is the issue with adding a leap day every four years?

• It causes a 24-hour discrepancy

• It aligns the calendar with the lunar cycle

• It makes the year too short

• It leaves us with 11 minutes too much each year

How do we adjust the leap year rule to maintain accuracy?

• Skip a leap year if the year is divisible by 100 but not 400

• Skip a leap year if the year is divisible by 200

• Add two days every leap year

• Skip a leap year every 10 years

When was the last century year that was not skipped as a leap year?

• 1900

• 1800

• 2000

• 2100

What is the new average discrepancy per year after adjusting the leap year rule?

• 30 seconds too much

• 20 seconds too much

• 15 seconds too much

• 26 seconds too much

How long would it take for the calendar to be one day off with the new leap year rule?

• 3333 years

• 2000 years

• 4000 years

• 1000 years

What humorous note is made about the long-term effects of the leap year adjustments?

• It will be fixed by technology

• We will solve it in 100 years

• It will never be a problem

• It's a problem for future generations
