Sunday Times Teaser 2733 – Letter Writing

Last year I went to calligraphy lessons. They were held weekly, on the same day each week, for nine consecutive months. Actually I only went to 15 of the lessons, and after the course was over I listed the dates of those lessons that I had attended. In order to practise my new skills I wrote the dates in words (in the format “First of January” etc) and I found to my surprise that each date used a different number of letters.
What were the dates of the first and last lessons that I attended?
