Meteorological Aumun started at the beginning of September

Why has the Met Office decided in their wisdom that autumn now begins
at the beginning of September (likewise the other seasons to the first
of the month)? The seasons have always been linked to the solstices and
equinoxes. Changing it is just confusing and there's no point to it.

Astronomical seasons start and end at the solstices and equinoxes.

Meteorological seasons start and end at the beginning of the months
containing the solstices and equinoxes.

Actual seasons don't match either, and vary from year to year.
