Happy Bonza Bottler Day. Bonza Bottler Day is any day that the date and month have the same number. Bonza Bottler Day is a "just because" kind of holiday started by Elaine Fremont, a day to cut loose, celebrate just for the joy of it, play. Bonza Bottler Day was first celebrated in Greenville, South Carolina and even has its own mascot (a dancing groundhog) and websites. TY Elaine Fremont.
