Day Function -- Part of the CometDate series of functions.

Syntax: Day(CometDate)

Discussion: The CometDate Day function extracts the Day of the week from a CometDate Date Serial Number. CometDates are based on a date of January 1, 1800. CometDates before that date are negative and after are positive. The Days extracted are: "Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"

This is a string function which yields the Full name of the Day in question. If you assign the result string to a 3 byte variable you may extract the 3 byte Day abbreviation.

The CometDate function respects the rules for leap years (i.e., the years 1800 and 1900 were not leap years, but the year 2000 is a leap year).

The practical range of CometDates is -657071 (01/01/01) to 2994623 (12/31/9999) but dates outside of that range may be usable in some contexts. There is no year 0 AD, The date goes from 1BC to 1AD.
