Humans have defined the length of a year based on the Earth's orbit around the Sun, which takes approximately 365.25 days. To account for the extra quarter day, we add a leap day every four years, resulting in a leap year of 366 days. This system is formalized in the Gregorian calendar, which is widely used today. The choice of a year length is fundamentally tied to astronomical observations and the need for a consistent framework for timekeeping.
What else can I help you with?
How did humans decide how long a year should be?
It was hardly a decision, it is the result of observing a physical cycle of the seasons or more accurately the position of the stars when observed from a fixed point on the earth. It takes one year for the pattern to repeat. A year is basically the time it takes for the Earth to make one orbit round the Sun.

What if your sixteen year old daughter has been going out with her boyfriend for a year is that too long?
Too long? She clearly is in love with him otherwise he wouldn't be her boyfriend. No one should be able to say they should break up because they have been together for too long. Feelings doesn't just end and if she wanted him to leave she herself would break up with him. No one else can decide for her what to feel.
