Hebrew Calendar: The Days of Creation and the Days of the Week

Shalom, everyone! On the Hebrew Calendar, a week is a cycle of seven 24-hour days, which mirrors the account of the seven-day period of the Creation of the Universe found in Genesis (Bereshit1:1 – 2:3. Through science, we learn the creation of the universe occurred over millions of years. Each day during Creation Week may not have been a literal 24-hour period. The Torah does not contradict science. One day from YAH‘s perspective may be thousands or millions of years from man’s perspective. YAH is Eternal, man is not.

The 24-Hour Day

The 24-hour day on the Hebrew Calendar consists of the evening and then morning: The evening is the period of the day from sunset to sunrise, 12 hours long. The morning is the period of the day from sunrise to sunset, 12 hours long:

“…And there was evening and there was morning, one day.” – Genesis 1:5

Unlike the day on the Gregorian calendar, which begins at midnight and runs until the following midnight, the day on the Hebrew Calendar begins at sunset and runs until the following sunset; for example, the first day of the week (Yom Rishon) begins on the preceding sunset of Saturday and runs until the following sunset of Sunday.

The Divisions of the 24-Hour Day

In ancient Yisrael, the 24-hour day was divided into six parts called “watches,” three watches in the evening (nighttime), and three watches in the morning (daytime). The following are the six watches of the 24-hour day kept by Bnei Yisrael when the Holy Temple stood in Jerusalem:

Time of the Day Division of the Day Hours of the Day
 Evening (Night-time)  First Night-time Watch  6 PM – 10 PM
 Second Night-time Watch  10 PM – 2 AM
 Third Night-time Watch  2 AM – 6 AM
 Morning (Daytime)  First Daytime Watch  6 AM – 10 AM
 Second Daytime Watch  10 AM – 2 PM
 Third Daytime Watch  2 PM – 6 PM

The Days of the Week

The names of the days of the week correspond to the day number upon which they fall within the seven-day week, beginning with the first day and ending with the seventh day or the Sabbath. The following are the seven days of the week on the Hebrew Calendar and their relation to the Creation Week:
