This program is free and is presented with no guarantees
or warrantees. The author accepts no liability for problems

DVD.COM - The program
DVDAYS is a perpetual calendar and calendar calculator
specifically written to run in a Desqview window. Its
date2days and days2date algorithms are perfect and
very efficient. * These algorithms account for 4 yr leap
cycles, 400 yr leap cycles and 100 yr no-leap cycles.
DVD can handle dates from 01/01/0000 through 12/31/65534
It's range is limited by the size of the computer var-
iable chosen for the year ( 16 bits ).
* Note
------
The gregorian calendar ( the one we use ) was established by
papal decree in the mid-1500's. Therefore, date calculations
by DVD for dates before that time will be mathematically
correct but not historically valid.

Special Keys
------------
1. F1 - F4 are menu selections ( self-explanatory ).
2. PGUP and PGDN change the displayed calendar a year
at a time.
3. UPARROW and DNARROW change the displayed calendar
a month at a time.
Entering Dates
--------------
DVD expects dates to have the following format:
MONTH(separator)DAY(separator)YEAR. The separators
can be just about any non-numeric character.
Examples
Enter DVD assumes
----- -----------
01-23-1990 = 01-23-1990
1 23 = 01-23-[current year]
1-23-1 = 01-23-1991 (assumes current decade)
1 23 01 = 01-23-1901 (assumes current century)
[RET] = Current date
