Is it possible to have three eclipses in one month? Yes, it’s possible. You can have two solar eclipses and one lunar eclipse in one month. Or you can have two lunar eclipses and one solar eclipse in one month.
However, it’s quite rare to have three eclipses in one calendar month. Follow the links below to learn more about past and future months in which there are three eclipses.
2000 July 01: Partial solar eclipse
2000 July 16: Total lunar eclipse
2000 July 31: Partial solar eclipse
Previous to July 2000, the last time three eclipses took place in one calendar month was in March 1904, when two penumbral lunar eclipses bracketed an annular solar eclipse.
1904 March 02: Penumbral lunar eclipse
1904 March 17: Annular solar eclipse
1904 March 31: Penumbral lunar eclipse
After July 2000, three eclipses will next occur within one calendar month in December 2206:
2206 Dec 01: Partial solar eclipse
2206 Dec 16: Total lunar eclipse
2206 Dec 30: Partial solar eclipse
According to the eclipse master, Fred Espenak, three eclipses fall in the same calendar month only twelve times during the five-century span from 1801-2300. Six times there are two solar eclipses and one lunar eclipse in one calendar month, and six times there are two penumbral lunar eclipses and a total (or annular) solar eclipse in one calendar month.

Three eclipses in one lunar month. Some might argue that the calendar month is an artificial constraint. Rather, it may be more appropriate to use the lunar (or synodic) month, which is a natural unit of time. A lunar month refers to time period between successive new moons, or successive full moons. So if we choose to base the three-eclipses-in-one-month phenomenon upon the lunar month, then three eclipses last occurred in one month earlier this year, in 2013:
2013 April 25: Partial lunar eclipse
2013 May 10: Annular solar eclipse
2013 May 25: Penumbral lunar eclipse
Previous to 2013, three eclipses last took place in one lunar month in 2011, and after 2013, will next occur in 2018:
2011 June 01: Partial solar eclipse
2011: June 15: Total lunar eclipse
2011 July 01: Partial solar eclipse
2018 July 13: Partial solar eclipse
2018 July 27: Total lunar eclipse
2018 Aug 11: Partial solar eclipse
Although it is rare for three eclipses to happen in the same calendar month, it’s not that terribly uncommon for three eclipses to occur in one lunar month. In fact, from the years 2000-2050, the three-eclipses-in-one-month phenomenon takes place a total of fourteen times. Six times, the lunar month features two solar eclipses and one lunar eclipse (2000, 2011, 2018, 2029, 2036 & 2047), and eight times, the lunar month presents two lunar eclipses and one solar eclipse (2002, 2009, 2013, 2020, 2027, 2031, 2038 & 2049).
Bottom line: It’s possible to have three eclipses within a single month. It’s rare to have three eclipses within a calendar month, but three eclipses within a lunar month is more common.
