The Julian calendar is a continuous count of days starting with 1 on January 1st and 365 on December 31st. A Julian clock is mainly used in programming, military, and food industries to calculate the number of days between two events. For example, food manufacturers and restaurants often use the Julian date to calculate storage and sell-by dates for their products. Similarly, pharmaceutical companies will also use the Julian date to calculate prescription expiration dates.
Our Julian Clock simultaneously shows the current time and Julian date in large, bright LEDs in red, green, or blue for easy viewing. Additionally, it accounts for daylight savings changes and leap years.
