Venus as an Evening Star, semi-technical summary
On April 19, Venus sets at Civil Twilight, when the sun is only 6° below the horizon at 30 minutes after sunset. During the next few evenings, begin looking for Venus about 2° above the west-northwest horizon at about 20 minutes after sunset. Use a binocular to first locate it. It is making its first evening appearance of this apparition.
On May 12, Venus – about 5° up in the west-northwest – is 1.2° to the right of the thin crescent moon. This is the closest Venus – moon grouping for this apparition.
A few nights later, on May 16, Venus – 6.0° up in the west-northwest – is 5.7° to the upper right of Aldebaran. This is a challenging observation as the star is only 3.0° in altitude. Use a binocular to see the scene.
On May 21, Venus sets at Nautical Twilight, when the sun is 12° below the horizon at 74 minutes after sunset.

July 1 – July 7, 2021, the waning crescent appears in the eastern sky. Early in the viewing period, the moon is among the dim stars of Pisces. As the week progresses, the moon wanes and moves farther eastward, appearing near Taurus.
