-
-
- 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.

- 01-23-1990 = 01-23-1990
- 1 23 = 01-23-[current year]

- 1 23 01 = 01-23-1901 (assumes current century)
