Prophecy is about time and events. The amazing part is God created time and then people used the sun, moon and earth to track His plan on His time. The Jewish holy days occur on specific days and the World Wars and Iraq Wars were fulfilled on these same days. See Jewish Calendar.

Come, and let us [Israel] return unto the Lord: for he has torn, and he will heal us; he has smitten, and he will bind us up. After two days will he revive us [1948]: in the third day [Atonement] he will raise us up, and we shall live in his sight (Hosea 6:1-2).

The years 2016, 2020, 2024 are leap years. On the Roman calendar, one day is added every four years to keep the calendar synchronized with the earth's orbit around the sun. Leap day is February 29. The Julian calendar was replaced by the Gregorian calendar which omitted three leap days every four hundred years.

God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years (Genesis 1:14).

The Muslim use a lunar calendar. There are twelve months with about 354 days in a year. Because there are no leap months, annual holidays such as Ramadan occur about eleven days earlier each year. After 33 short years, the calendar is one year ahead of the Roman calendar.

The Jewish calendar differs from the Roman calendar. Days begin at sunset. Months begin with the first observation of the new crescent moon. The Jewish culture has two major new years. The religious new year begins in the spring on the 1st of Nisan and the civil new year begins in the late summer or early fall on the 1st of Tishri. Genesis is beginning. The Jewish name is Aleph b'Tishri. On Rosh Hashanah or the Feast of Trumpets, one year is added to years from creation. The current year is 5776 AM based on Rabbi Yose ben Halafta's chronology. The year is missing about 214 years so it is closer to ~5990 AM. As God created the world in six days, human rule lasts for 6000 years. See Jewish New Year.

The Lord spake unto Moses and Aaron in the land of Egypt saying, This month (Nisan) shall be unto you the beginning of months: it shall be the first month of the year to you (Exodus 12:1-2).

In the beginning (Aleph b'Tishri), God created the heavens and earth (Genesis 1:1).

The Jewish calendar has a leap year. A regular lunisolar calendar has twelve months for a total of about 354 days. A thirty days month of Adar I (Adar Aleph) is added after Shevet and before Adar, giving thirteen months. This keeps the calendar synchronize with both lunar months and solar years. A leap year is added every two or three years.

By 358 AD, Hillel II, leader of the Jewish Sanhedrin, implemented a perpetual calendar with a nineteen-year cycle. Seven years are leap years. There are certain postponement rules so a high Sabbath is not next to a regular Sabbath. Looking back in history, we can estimate when holy days occur based on phases of the moon.

Let no man therefore judge you in meat, or in drink, or in respect of an holy day, or of the new moon, or of the sabbath days: Which are a shadow of things to come; but the body is of Christ (Colossians 2:16-17).
