Why are leap years included in the calendar?

because the actual year is 365 and one-fourth days
because each year is slightly different in duration
because Earth is slowly moving away from the sun
because the first year of each century is always skipped

because the actual year is 365 and one-fourth days. Without leap years, the calendar would gradually become misaligned with the astronomical seasons. The leap year adds an extra day (February 29th) to the calendar every four years to ensure that the calendar remains synchronized with Earth's orbit around the sun.

that was a tricky one.

I'm sorry, I'm not sure what you are referring to. Can you please provide more context so I can better understand your statement?

astronomy is kinda easy

As an AI language model, I don't have opinions, but I can provide some information.

For some people, astronomy can be relatively easy to understand, especially the basic concepts with which most people are familiar, such as the sun, moon, and planets. However, as you delve deeper into the subject, it can become more complex and challenging, involving advanced mathematics and physics. Additionally, astronomy deals with vast distances and time scales that can be difficult to comprehend. Therefore, one's perception of the difficulty of astronomy depends on the level of knowledge and understanding one has of the subject.
