Example Date julian 001

 

 

Description

These examples use the julian function to convert the Text or normal Date-formatted arguments into a numeric Julian Date format.

 

Details

Text is converted into a numeric Date format.

(julian "7/4/1992") Returns: 727747.0

The standard Date format is converted into a numeric Data format.

(julian #Jul,4,1992) Returns: 727747.0
(julian "1/2/-1000") Returns: -365241.0

Notes and Hints

The Julian form of a date is useful when it is necessary to perform arithmetic computations with a date. However for human-readability, it is more convenient to view a date as a string. The Lisp string function is capable of converting a Date object to a String object. Since the Julian function returns a Number, it is necessary to coerce the Julian date to a Date object first, and then convert the Date object to a String object:

(string (date 713882.75))

Returns: #Jul,19,1954:18:00:00

(string (date 727763) )

Returns: #Jul,20,1992

(string (date -365249) )

Returns: #Dec,25,1001BC
