Questions

Is the first day of fall always on the same date?

No. In Eastern Time it falls on September 22 and September 23 between 2026 and 2035, because a year is not exactly 365 days long.

What time zone are the times in?

Eastern Time (EST or EDT). For Central Time subtract one hour, for Mountain two, for Pacific three. Late in the evening the date can be a day earlier out west.

What is the difference between astronomical and meteorological seasons?

Astronomical seasons start at the equinoxes and solstices. Meteorologists use whole months: fall from September 1 for three months.
