Just curious : what do you understand by calendar month ?
My understanding is from the 1st - 30th / 31st.
In other words, if you resign the 14th, 21st or 31st of March - your calendar month starts from 1 April and final day 30 April. At worst case, you're looking at 30 days but this could be up to 59 days depending on the date you hand in ? Obviously most people hand in the 31st March - but I see the same result if handed in earlier.
