World UFO Sightings Daily Histogram

World Daily UFO Sightings
Histogram

UFO sightings counts are graphed for every day of the year to show seasonal variation.

Data for all countries, and for all years, is combined here.   Only UFO sightings with inaccurate dates are excluded.

An 11-day running-average is shown as a white curve to smooth the data.

Major meteor showers are shown in colors.   Only the Taurids (early November) correspond to a peak in UFO sightings.

See numerical   Monthly Counts   for all times and places combined.

Here are Monthly Histograms, broken down
