Julian Time

Julian time, also known as Julian Date (JD), is a system used to represent time in astronomy. It is a continuous count of days and fractions of a day since noon on January 1, 4713 BCE. In calculating the position of the sun, Julian time is used because it provides a standardized and consistent reference for precise timing and synchronization of observations. By converting specific dates and times into Julian time format, astronomers can accurately determine the sun's position at any given moment. This is crucial for various applications, including determining sunrise, sunset, and other solar events for purposes such as calculating prayer times, astronomical observations, and celestial navigation. Julian time ensures that calculations involving the sun's position are accurate, reliable, and universally consistent across different locations and time zones.
