In astronomy, the term blood moon refers to a complete lunar eclipse which causes the moon to appear red. The moon looks red due to dispersed light from Earth's sunrises and sunsets that is refracted back onto the moon's surface.
The moon will be located in more or less the eastern part of the sky when it rises, and in more or less the western part of the sky when it sets. Between rising and setting, it will be found in the southern part of the sky.
A blood moon is a deep reddening of the moon caused by the Earth passing between the moon and the sun. During the period of the eclipse, light from the sun passes around the Earth and through its atmosphere. This scatters the short-wavelength blue light from the sun but allows the longer-wavelength

Websites such as Timeanddate.com provide sunrise and sunset times for locations all around the world. Printed and online almanacs also traditionally provide sunrise and sunset times as well as times for civil, nautical and astronomical twilight; moonrise and moonset times; and information about the
The dates of the 2015 blood moons are April 4th and September 15th. These dates are the final two of the 2014 to 2015 Lunar Tetrad, the first two being April 15th and October 8th of 2014.
The prophecy of the four blood moons is the claim that four consecutive lunar eclipses that coincide with Jewish holidays signal a major event for the Jewish people. Possible events that have been theorized for 2015 include the final 7 years before Armageddon and the second coming of Jesus Christ.
