Mars retrograde dates in 2045
Mars has no station in 2045 and is direct all year.
Mars turns retrograde about every 26 months, and each retrograde lasts between 60 and 81 days. Between one retrograde and the next lie roughly 25 to 27 months, so some calendar years have no Mars station.
A retrograde of Mars is centred on its opposition to the Sun, when the Earth overtakes it. In tradition Mars stands for energy, drive and assertion, and astrologers who follow retrogrades read a Mars retrograde as a time to revisit them. That is a tradition of interpretation, not a measured effect.
Stations in 2045
No station of Mars falls in 2045.
Stations are found by Astrely's own code from the planets' positions and are shown in Nicosia time. Mercury's stations are checked against NASA/JPL Horizons to within four minutes; the outer planets move so slowly around a station that their times are best read to the day. The method page has the details.
