Parent and Child Day (Earth-2356)

The Parent and Child Day is a holiday in Coruscant. Coruscant's various merchants anticipate a unique business opportunity for the holiday and bombard the Galactic Emperor's office with requests to set up additional stands in Coruscant's streets.

Many stores also sell special items for the day: Lightning Burger sells a unique spicy burger, advertised as the "Challenge of the Lightning God".

Parent and Child Day is a very successful holiday, attracting visitors to Coruscant from all over the galaxy. The planet's annual food competition also ends up falling on Parent and Child Day, adding to the variety of the day's activities. Because of how well-received Parent and Child Day becomes, the Emperor was asked to create additional holidays for everyone who lacked a parent or child, such as "Husband and Wife Day", "Older and Younger Sister Day", and "Alone Day".
