Day
Definition- A Day is the amount of time the Earth takes to rotate once around its axis approximately 86,400 seconds.
Origin- The term day originally referred to one full rotation of the Earth. Since 1960, it has been scientifically defined in terms of seconds. Later, in 1967, with the introduction of atomic time measurement, time became more precisely calculated based on atomic transitions.
Current Use- A Day commonly represents a 24-hour ...

Definition- A Day is the amount of time the Earth takes to rotate once around its axis approximately 86,400 seconds.
Origin- The term day originally referred to one full rotation of the Earth. Since 1960, it has been scientifically defined in terms of seconds. Later, in 1967, with the introduction of atomic time measurement, time became more precisely calculated based on atomic transitions.
Current Use- A Day commonly represents a 24-hour period. It is also used informally to describe the daylight hours between sunrise and sunset, or as a way to refer to specific calendar days, such as weekdays or holidays.
Year
Definition- A year is the time taken by the Earth to complete one full orbit around the Sun roughly 365 days. This period determines the changing of seasons and patterns in weather, vegetation, and daylight hours.
Origin- The concept of a year has evolved over time. Different calendars have used different definitions:
• The Julian calendar introduced the leap year system.
• The Gregorian calendar, which we use today, refined the calculation to make the calendar year align more accurately with Earth’s orbit.
Current Use- A year is used globally as a standard time unit for civil, academic, and fiscal purposes. Variations like leap years, financial years, and academic years are based on specific needs. In scientific contexts, the Julian year (based on seconds) is also used.
Day to Year Conversion Formula
1 day = 0.0027378508 years
1 year = 365.25 days
Formula:
To convert days to years: Years = Days × 0.0027378508
Example
Convert 100 days to years: 100 × 0.0027378508 = 0.2737850787 years
So, 100 days = 0.2738 years (approximately).
