May’s big day on the Calendar is Mother’s Day on the 12th. Need I say more. This is the 3rd largest retail holiday in the US so get thinking about designs now.
Get your geek on May 4th with Star Wars Day. “May the 4th be with you”.
Memorial Day finishes out the month to honor our soldiers and show some patriotic pride.
Though May has some well known holidays in it, keep in mind the holidays that may not be in the limelight. This allows you to focus on some niche markets that are not overly saturated and find high traffic keywords that aren’t overused.
