Looking at the "Tue" column: April 2nd, 9th, 16th, 23rd, 30th
First Tuesday: April 2nd
Second Tuesday: April 9th
Third Tuesday: April 16th
Counting days: April 1st (Mon), 2nd (Tue) = 1st Tue, 9th (Tue) = 2nd Tue, 16th (Tue) = 3rd Tue
Sarah's birthday is April 16th

Looking at the calendar, May 24th falls in the Friday column
It will be Friday, May 24th
