I have been told two conflicting answers on this question. It was my understanding that when you give up something up for Lent you do it for the entire Lenten season. Then I heard that you can forgo the weekends i.e. if you gave up sweets you can have them on the weekend but get back on track for the week. Can you please verify this for me as we will be going into the Lenten Season in the next month or so.
