Tip 44: Dates to Avoid 

Be careful when choosing future show dates that you do not exclude large segments of your target audience.We all know the obvious dates to avoid: New Year's, Passover, Good Friday/Easter, Memorial Day, July 4, Labor Day, Rosh Hashanah, Yom Kippur, Thanksgiving and Christmas.

Also, many shows avoid being too soon after New Year's or Labor Day because the major promotion effort will occur during December and August—bad months to get anyone's attention.

Yes, following all this advice would severely limit your available dates.  But do be aware of who you will be excluding by choosing certain dates.
