Calendars and Time

Time is a complex concept that has been pondered by scholars and philosophers throughout history. In the Jewish tradition, time holds great significance.

Time can be seen as a vessel for the unfolding of events and the opportunity for growth and transformation. In the Hebrew Bible, we encounter the idea of time in various ways. One of the crucial aspects is the concept of a cyclical pattern of time found in the weekly, monthly, and annual cycle. The cycle provides a rhythm that allows us to pause, reflect, and rejuvenate. It reminds us of the importance of taking a break from our daily pursuits and connecting with the Divine.

The Jewish calendar is lunar-based, which means that it follows the cycles of the moon. This lunar calendar consists of months that begin with the sighting of the new moon. The annual cycle of events like Passover, Shavuot, and Sukkot, align with significant agricultural moments, emphasizing our connection to the land and the changing seasons. Moreover, time is perceived as an opportunity for growth and spiritual development.

In Psalm 90:12, it is written, "So teach us to number our days, that we may gain a heart of wisdom."

This verse encourages us to recognize the precious nature of time and to utilize it wisely, focusing on personal and spiritual growth.

While time remains a mysterious and elusive concept, Judaism reminds us to cherish each moment, to be present and intentional in our actions, and to use the gift of time to deepen our relationship with the Divine and with others.

The Gregorian Calendar

The Gregorian calendar is the most widely used civil calendar system in the world today. It was named after Pope Gregory XIII, who introduced it in 1582 as a modification of the Julian calendar. The primary goal of the Gregorian calendar was to address issues with the Julian calendar, which was drifting out of sync with astronomical events. The Julian calendar had an error of about 11minutes and 14 seconds per year, which accumulated over time. This discrepancy left to the misalignment of the calendar with the solar year, meaning that the seasons were gradually shifting earlier on the calendar.

The Gregorian calendar made several adjustments to rectify this problem. In order to realign the calendar with the solar year, ten days were omitted following October 4th, 1582, with the date jumping directly to October 15th. The Gregorian calendar also modified the leap year rule. While the Julian calendar added a leap day every four years, the Gregorian calendar excludes three leap days every 400 years, resulting in an average year length of 365.2425 days. The adoption of the Gregorian calendar varied across countries and regions over time. Catholic countries, being under the influence of the Catholic Church, were among the first to adopt it. Protestant countries, however, were more reluctant to adopt the changes associated with a Papal decree. It was not until the nineteenth and twentieth centuries that many countries officially transitioned to the Gregorian calendar. The Gregorian calendar is widely used for secular and civil purposes, the Jewish calendar, as mentioned earlier, is still used for determining Jewish events and religious observances within the Jewish tradition.

The Julian Calendar

The Julian calendar was a calendar system introduced by Julius Caesar, in 45 BCE. It was created as a reform of the Roman calendar, which had significant inaccuracies and inconsistencies. The Roman calendar, had a year of only 355 days. In order to align the calendar with the solar year, an additional month of 22 or 23 days known as "intercalary month," was inserted every few years.

However, the calculation of the intercalary month was often misused for political purposes, leading to confusion and manipulation. Upon the advice of astronomer Sosigenes of Alexandria, Julius Caesar decided to reform the calendar system. The new calendar known as the Julian calendar was more closely aligned with the tropical year, the time it takes for the Earth to complete one orbit around the sun. The Julian calendar introduced a year of 365.25 days, with a leap day added every four years. This leap day occurred at the end of February and consisted of an additional day, making it a 366-day year. With this adjustment, the average length of the Julian year was 365.25 days, closely approximating the 365.2425-day length of the solar year.

The Julian calendar was widely adopted throughout the Roman Empire and remained in use for many centuries. It had a considerable impact on the Western world and served as the foundation for the development of subsequent calendars. As mentioned above though, it had discrepancies and miscalculations that were later adjusted by the Gregorian calendar.

BCE (Before the Common Era)

In reference to BCE- it is a more secular alternative to the traditional Christian dating system previously denoted as BC (Before Christ). The use of BCE is commonly employed by scholars and historians, particularly in academic and non-religious contexts, to provide a neutral and inclusive way of referring to dates before the assumed birth of Jesus Christ. The adoption of BCE as a dating system is a way to respect and acknowledge diverse cultures and religious beliefs.

Instead of using terminology that assumes a particular religious perspective, BCE provides a standardized and universally accepted notation for chronological references, regardless of religious affiliation.

AD (Anno Domini, The Year of Our Lord)

In reference to A.D.- it is used to designate years in the Gregorian calendar that are counted since the approximate time of Jesus Christ's birth. The use of A.D. as a dating system emerged in the medieval period and gained widespread adoption in Western Europe. The initial reference point for this system is traditionally considered to be the year of Jesus' birth, although the precise dating has been subject to debate among scholars.

Recently, there has been a shift towards a more inclusive dating system. To avoid a religious bias or assumption about the significance of Jesus Christ, some scholars and historians use the Latin abbreviation "C.E." (Common Era) as an alternative to A.D.. This allows for a more neutral and inclusive designation for the same time frame.

The demarcation between BCE and CE which replaced AD, is determined by the same historical event- the approximate time of the birth of Jesus Christ. BCE denotes the years before this event, while CE refers to the years afterward. The notation does not affect the actual historical timeline; it simply offers a way to communicate dates without assuming a specific religious framework.

The Solar Calendar

The solar calendar is a calendar system that primarily follows the cycles of the sun for measuring the passing of time. It is based on the solar year, the time it takes for the Earth to complete one orbit around the sun. In a solar calendar, the year is divided into specific units, typically referred to as months, which correspond to the Earth's position relative to the sun.

The length of each month is determined by the number of days it takes for the Earth to complete a full revolution around the sun. Many cultures and civilizations have developed solar calendars throughout history, each utilizing different methodologies and adjustments to account for the slight variations in the exact duration of the solar year.

The Lunar Calendar

The lunar calendar is a calendar system that follows the cycles of the moon for measuring the passing of time. It is based on the lunar month, which is the time it takes for the moon to go through its complete cycle of phases, from a new moon to a new moon. In a lunar calendar, the months typically begin with the slighting of the new moon. The length of each month is determined by the time interval between one new moon and the next, which is approximately 29.5 days. Due to the fact that the lunar month is shorter than the solar month, a purely lunar calendar would gradually drift out of alignment with the solar year. To reconcile this discrepancy, some lunar calendars incorporate intercalary months, which are added periodically to bring the lunar calendar closer to the solar year. The specific rules for adding these extra months may vary in different lunar calendar systems.

The Jewish calendar, known as the Hebrew calendar, is an example of a lunisolar calendar. it is predominantly based on the lunar cycle, with each month beginning with the sighting of the new moon. However, the Hebrew calendar also incorporates adjustments to ensure that the events and agricultural seasons align with the appropriate times of year in the solar cycle. This is achieved by adding intercalary months, such as Adar II, in specific years.

The lunar calendar has been widely used in different cultures and traditions throughout history. It serves as a practical system for determining the timing of religious observances, events, and other cultural and social activities.
