Slowly Stamp
Fibonacci Day
Honours Leonardo Fibonacci and the sequence reflected in the date 11/23
Beginning 1, 1, 2, 3, this number sequence continues by adding the previous two numbers. Its connection with the month-first calendar notation inspired this informal observance. Leonardo of Pisa introduced it to European readers through a rabbit problem, although related patterns had already been studied in Indian mathematics.
