The above calendar program, created under the supervision of Carl Franklin, can be used for both a quick way to look up dates for God's annual Holy Days and for in-depth research.
God’s holy days were given to mankind to reveal His plan of salvation, a divine plan that the human mind could never comprehend without this revelation. Each of these appointed times has a special meaning related to salvation, and each pictures a major event in God’s plan. The first holy day that is listed in Leviticus 23 is the weekly Sabbath.
Every calendar in the history of man has attempted to measure time by either the solar or the lunar cycle. The calendar we use today is a solar calendar. Because it is a solar calendar, its months are synchronized with the equinoxes and solstices of the solar year.
The 365 days in the solar year are divided into four months with 30 days (30 x 4 = 120), seven months with 31 days (31 x 7 = 217), and one month with 28 days (120 + 217 + 28 = 365 days). Although the calendar year is 365 days, the actual solar year is 365.2425 days. The fraction of a day (approximately ¼ day) is made up by adding one day to February every 4 years.
Because we live in a culture that uses this calendar, it governs our days and months of worship. It governs our work schedules, vacations, graduations, weddings and funerals. It governs our financial system. All businesses, large and small, depend on the calendar to set dates of contracts, interest schedules, tax schedules and billing periods.
The Hebrew Calendar served the same purposes for banking and commerce in ancient times. However, its most important function was, and still is, to set the dates of the annual holy days that God established at the creation of the world.
