Counting the Days

The number of letters in "Monday" is 6; for the other days it's 7, 9, 8, 6, 8, 6.  If these are added together daily, the total on day 44 is 313, a palindromic prime*.

Find at least four other palindromic primes* that occur as the days pass and are totalised.

*A palindrome is a word (in this case a number) that is the same whether read forwards or backwards.  A prime number is any number divisible only by itself and 1.
