Calendar in VB
This program has been written by two authors: Refik Hadzialic [email protected] and Sergiy Bondarenko Here is VB version of a Calendar program which has been originally written in C: This program displays days of a month on a screen in a calendar format, from given month and year, which inputted from the keyboard. Dates range: -4712 (4713 B.C.) to 9999 years. Background information: Julian Caesar implemented the Julian calendar, which was in use until 1582 year (in England and some other countries until 1752 year). This calendar produced a difference between actual days in a year (one Earths orbit around the Sun) and its date. So Pope Gregory reformed calendar in October 1582. The astronomers chosen point time to begin from was 12 o’clock noon (Greenwich Mean Time) on 1st January 4713 B.C. The program allows to find which days of the month fall on which dates in a stated above range of years. The dates (for February in the leap years) before 1582 year calculated in a different way than after it. Using algorithm from this program any date can be calculated without limits.
