It so happens that September's Friday the 13th also happens to be Full Moon. What sets this full moon apart from others is that farmers can work late into the night by its light, as it rises around the same time as the sun sets, according to the Farmers Almanac. The next one isn't expected to happen again for another 30 years - on August 13, 2049.

And what's more, depending on where you live, the rare "micromoon" could be extra spooky this year as it is set to appear on Friday 13. Many trace that reputation back to the Bible, where Christ ate with 12 apostles - included Judas, who betrayed him.

What makes the Harvest Moon unique is that rather than rising its normal average of 50 minutes later each day, the moon rises at almost the same time each night leading up to when it's full.

Friday's moon is also considered a "micro moon" because it will appear about 14 percent smaller due to its distance from Earth. The Friday the 13th won't be quite as rare in the Eastern time zone because the full moon technically happens just after midnight on the 14th. Those in the central, mountain or pacific time zones will be able to see the full moon before midnight on September 13.

The last time there was a split time zone full moon was on June 13, 2014.
