Venus and Mars will share the same right ascension, with Venus passing 29' to the north of Mars.
At around the same time, the two objects will also make a close approach, technically called an appulse.
From Fairfield , the pair will become visible around 20:45 (EDT), 12° above your western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 1 hour and 31 minutes after the Sun at 21:56.
Venus will be at mag -3.9, and Mars at mag 1.8, both in the constellation Leo.
The pair will be close enough to fit within the field of view of a telescope, but will also be visible to the naked eye or through a pair of binoculars.
A graph of the angular separation between Venus and Mars around the time of closest approach is available here.
The positions of the two objects at the moment of conjunction will be as follows:
|Object||Right Ascension||Declination||Constellation||Magnitude||Angular Size|
The coordinates above are given in J2000.0. The pair will be at an angular separation of 28° from the Sun, which is in Gemini at this time of year.

The circumstances of this event were computed using the DE430 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).
This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
