Convert one year to days

Explanation

To convert one year to days all we need is to know the conversion factor and we are done. Luckily, we can compute that factor using the units' definitions below.

The result is that there are 365 days in 1 year.

Formula

1 y = 365 d

yearsy

dimension	time
symbol	y

The year (y) is a unit of measurement of time.

The unit is based on a year of 365 days of 86400 seconds each and is therefore equal to a common year in the Gregorian calendar.

It is different from the tropical year (the actual year or complete cycle of seasons), the sideral year (the time taken by the Earth to orbit the Sun once with respect to the fixed stars) or the julian year (the average year in the Julian calendar).

Definition of the year

One year is equal to 31536000 seconds.

The day (d) is a common unit of measurement of time. It is accepted for use with the SI.

One day can be divided into 24 hours of 3600 seconds each and 365 days make a year.

Some Facts

The longest period of sleep deprivation scientifically documented is 11 days. That is not something you want to try though, like other animals, humans need regular sleep for their brain to function correctly. The symptoms of a lack of sleep can be light at first. They include moodiness, irritability and a shorter attention span. But after days of sleep deprivation the patient can suffer from hallucinations, paranoia and even die. So turn off netflix, it's not worth it.

A sexagesimal system

Hours, minutes and seconds are an example of a sexagesimal or base 60 numeral system.

The number 60 is a superior highly composite number, meaning it has a lot of factors. This allows for some simplification when dividing.

Since there are 60 minutes in an hour, the hour can be divided evenly in eleven different ways (with sections of 30, 20, 15, 12, 10, 6, 5, 4, 3, 2 and of course 1 minute).

Coming up with and remembering 60 different symbols would be cumbersome, that is why we write the sexagesimal digit using the decimal system.
