I assume he didn't attend school on the 17th, so that is day 1.

To find out the number of days Gillian missed school from 17th January 2012 to 4th February 2012, we need to count the total number of days within that period, excluding both the start and end dates.

First, let's find the number of days in January between the 17th and the end of the month. January has a total of 31 days, so the number of days after the 17th is 31 - 17 = 14.

Next, let's find the number of days in February between the start of the month and the 4th. February has 29 days in a leap year (which 2012 is), so the number of days until the 4th is 4.

Now, let's add up the number of days in January and February: 14 + 4 = 18.

Therefore, Gillian missed school for a total of 18 days.
