The kabbalists used the 49 days (7 X 7) to form permutations of various sefirot denoting the ascent out of the 49 "gates" of impurity of the Egyptian bondage to the purity of the revelation at Sinai. In many prayer books these combinations are printed at the side of each day listed.
In order not to forget the count of the day it was fairly common practice to have an "Omer calendar" in the home with movable numbers on it. These "calendars" even developed into an art form and several early specimens show intricate work and lettering. .
