It felt like fall for real here in Albuquerque last evening at the end of a spectacularly beautiful day.
If you’d like to synchronize your calendars, the equinox is Sunday the 23rd at 9:51 Universal Time. That’s the fall equinox in the northern hemisphere; spring in the southern.
Subtract 4 hours for Eastern Daylight Time, 5 for Central, 6 for Mountain and 7 for Pacific.
Or, in other words, fall begins at 3:51 a.m. Mountain Daylight Time on Sunday.
