Length of the Synodic Month: 2001 to 2100


Introduction

The most well-known lunar cycle is the familiar rhythm of the Moon’s phases. The Moon has no light of its own but shines by reflected sunlight. So the geometry of its orbital position relative to the Sun and Earth determines the Moon’s apparent phase.

The synodic month is the formal name for the cycle of the Moon's phases. The mean length of the synodic month is 29.53059 days (29d 12h 44m 03s). This is nearly 2.21 days longer than the sidereal month (Moon's motion with respect to the stars). As the Moon revolves around Earth, both objects progress in orbit around the Sun. After completing one revolution with respect to the stars, the Moon must continue a little farther along its orbit to catch up to the same position it started from relative to the Sun and Earth. This explains why the mean synodic month is longer than the sidereal month.

New Moon is defined as the instant when the (geocentric) ecliptic longitudes of the Sun and Moon are equal. The synodic month is measured from New Moon to New Moon, and it is sometimes referred to as a lunation. Historically, the phases of the Moon have been used as the basis of lunar calendars by many cultures around the world. The major problem with such calendars is that the year, based on the solar calendar, is not evenly divisible by a whole number of lunations. Consequently, most lunar calendars are actually luni-solar calendars (e.g., Chinese, Hebrew, and Hindu) that include intercalary months to keep the seasons in step with the year.

The duration of the lunation actually varies from its mean value by up to seven hours. For instance, table below contains details for all lunations in 2001. The first column lists the date of every New Moon throughout the year (GMT), while the second column gives the duration of each synodic month. The third column is the difference between the synodic month and its mean value. The first lunation of the year (Jan 24) was 06h 30m longer than the mean. Continuing through 2001, the length of each lunation drops and reaches a minimum of 05h 33m shorter than the mean value (Jul 20). The duration now increases with each succeeding lunation reaching a value of 03h 57m longer than the mean by year's end (Dec 14).

What is the cause of this odd behavior? It involves the perigee and apogee (farthest from Earth) points of the Moon's orbit with respect to New Moon. Figure 1 shows the elliptical orbit of the Moon around Earth. When the Moon is at perigee, it is nearest to Earth. At apogee, the Moon is at its greatest distance from Earth. The Moon's true anomaly is the angle between the point of perigee along the Moon's orbit and the position of the Moon itself. In other words, it is the orbital longitude of the Moon with respect to perigee.

The last column in table above contains the Moon's true anomaly at the instant of New Moon. The table shows that when New Moon occurs near perigee (true anomaly = 0°), the length of the synodic month is at a minimum (e.g., Jul 20). Similarly, when New Moon occurs near apogee (true anomaly = 180°), the length of the synodic month reaches a maximum (e.g., Jan 24). (for a more detailed explanation, see: Moon's Orbit and the Synodic Month.)

True Anomaly

A smaller, secondary effect involves Earth's elliptical orbit around the Sun. If a perigee New Moon occurs when Earth is at perihelion (closest to the Sun), the synodic month is a bit longer than when Earth is at aphelion (furthest from the Sun). On the other hand, an apogee New Moon produces shorter synodic months when Earth is at aphelion as opposed to perihelion.

The table below lists the date of every New Moon (GST) and the length of the corresponding synodic month during that lunation. The difference in the length of the synodic month from it's mean value is listed next. Finally, the longest and shortest synodic months for each year are noted.

During the 100-year period covered in this catalog, there are 1236 complete lunations. The shortest lunation begins on 2053 Jun 16 at 10:51 GMT and lasts 29d 06h35m (06h 09m shorter than the mean). The longest lunation begins on 2017 Dec 18 at 06:31 GMT and lasts 29d 19h47m (07h 03m longer than the mean). Thus, the duration of the lunation varies over a range of 13h 12m during this century.

Extreme Synodic Months During the 21st Century

During the 100-year period covered in this catalog, there are 1236 complete lunations. The shortest lunation begins on 2053 Jun 16 at 10:51 GMT and lasts 29d 06h35m (06h 09m shorter than the mean). The longest lunation begins on 2017 Dec 18 at 06:31 GMT and lasts 29d 19h47m (07h 03m longer than the mean). Thus, the duration of the lunation varies over a range of 13h 12m during this century.
