Is a count a continuous variable?
Continuous variables can take on any value on a number line, whereas discrete variables can take on only integers. This is important in statistics because we measure the probabilities differently for discrete and continuous distributions. A count variable is discrete because it consists of non-negative integers.
How is Julian day number calculated?
The Julian day number is based on the Julian Period proposed by Joseph Scaliger, a classical scholar, in 1583 (one year after the Gregorian calendar reform) as it is the product of three calendar cycles used with the Julian calendar: 28 (solar cycle) × 19 (lunar cycle) × 15 (indiction cycle) = 7980 years.
What is Julian day?
The Julian day or Julian day number (JDN) is the number of days that have passed since the initial epoch defined as noon Universal Time (UT) Monday, 1 January 4713 BC in the Julian calendar. That noon-to-noon day is defined as Julian day 0. Thus all JDNs that are evenly divisible by 7 are Mondays.
Is birthday a continuous variable?

What does Julian date look like?
The first number of the Julian Date represents the year. The last three numbers represent the day that it was manufactured. So for example, if the manufacture date was listed as 1067 that would mean that the MRE was manufactured on March 7, 2011.
What is the Julian date for eggs?
The Julian date is the “pack date,” when the eggs were washed, graded and place in the carton. This three-digit code represents the consecutive day of the year, with January 1 as 001 and December 31 being 365. The Julian date is usually found on the short side of the carton.
Is age a discrete or continuous variables?
We could be infinitly accurate and use an infinite number of decimal places, therefore making age continuous. However, in everyday appliances, all values under 6 years and above 5 years are called 5 years old. So we use age usually as a discrete variable.
