Are we there but? Have we reached the equinox?
In Pittsburgh the iciness solstice invariably arrives on 21 December, however the twenty first by no means works for the autumnal equinox.
As an astronomical tournament, the equinox arrives all over the place on Earth at precisely the similar second however is expressed as other dates and occasions as a result of longitude and time zones. Hawaii’s equinox is at the twenty second whilst Paris and Johannesburg have the similar date and time as a result of time zones.
| Common Time | 23 Sep, 6:50AM UTC |
| Pittsburgh | 23 Sep, 2:50 AM EDT |
| Honolulu, HI | 22 Sep, 8:49?PM HST |
| Tokyo | 23 Sep 22, 3:49?PM JST |
| Paris | 23 Sep, 8:49AM CET |

For many of the Earth this month’s equinox will happen at the twenty third. When it does everybody’s sundown might be precisely west, similar to the photograph above.
