Sunday Times Teaser 2738 – Prime Day for the Irish

by H Bradley and C Higgins

March 17th is a prime day since the month number, the day of the month, the length of the month’s name and the number of days in the month are all prime.

My friend then told me whether these properties are prime or composite for his birthday this year, adding that if he also told me the day of the week on which it occurs I would then be able to work out its date.

What is the date of his birthday?
