September

September is the month when spring starts in the Southern Hemisphere and autumn starts in the Northern Hemisphere.

On or round the 23rd of September the days and nights are of equal length throughout the World, that is known as the spring equinox in the southern hemisphere and the autumn equinox in the northern hmisphere. The other month when there is an equinox is March.

Since early in the 21st Century September has been remembered as the month when the terrible September 11, 2001 attacks happened in New York City and at the Pentagon.
