Today is Day 53 of 2019

53

is the only two-digit number that is reversed in hexadecimal (base 16): 3516

xy + x + y never yields 53.

the chance that no pair of 53 people in a room have the same birthday is approximately 1/53.

is the sum of five consecutive primes: 5 + 7 + 11 + 13 + 17
The sum of all consecutive prime numbers from 7 to 53 is the product of 7 x 53:
7 x 53 = 7+11+13+17+19+23+29+31+37+41+43+47+53 = 371

53 = 22 + 72 (sum of squares)
535 = 418,195,493 = (4+18+1+9+5+4+9+3)5
537 = 1,174,711,139,837 = (1+1+7+4+7+1+1+1+3+9+8+3+7)7

Many thanks are extended to Archimedes' Lab for their information.
