Desirability is determined by the phase of the Moon. The moon is spectacular, very desirable for a star party. Such dates are:
2017: Start Time April 29 - 30 9:00 PDT -- began March 12, 2017 May 1 - 3 9:00 PDT High Schools May 28 - 31 9:30 PDT High Schools
Dates with no moon in the evening sky are more plentiful. There are many star clusters, colorful double stars, etc., so the sky is very rewarding. Consider:
2017: Start Time April 25 - 27 9:00 PDT High Schools May 14 - 22 9:15 PDT High Schools May 23 - 25, 27 9:30 PDT High Schools
Too much moon (over 75% illuminated) makes it difficult to show anything but a few bright objects, so we try to stay away from the nearly-full moon. It's a poor show, and not fair to the students (nor to the astronomers).

** Not recommended for elementary nor for middle schools.
Optional details about start times:
Ideally, a star party should run two hours, allowing time for everyone to look through each telescope, then move some of the scopes to additional targets. But ninety minutes is a practical minimum.
In addition, allow 90 minutes before the start time for the astronomers to set up, and 30 minutes afterward to pack the telescopes.
- Start times are approximately one hour after sunset. More specifically, they are at "Nautical Twilight": the time when the sun is 12 degrees below the horizon. It is rounded to the nearest 15-minute interval.
- The time from sunset to nautical twilight varies from about 58 to 70 minutes; it is minimum about November 20 and January 20, and maximum about June 21, varying slightly by year. They depend on the site's latitude, 37.3 degrees north.
- The start times depend on both latitude and longitude; the latter is 121.9 degrees west.
