"A moveable holiday is one that can take place on a different date from year to year. The date may be set using a different calendar, such as a solar calendar (which is based on the 365 days it takes the Earth to revolve around the Sun) or a lunar calendar (in which each of 12 months begins with a new moon and ends 29.5 days later), or by law or by tradition. For example, Thanksgiving is a moveable holiday because it takes place on the fourth Thursday in November, thus falling on a different date each year." enotes.com
