<div>Hello All, it has been a few months since I have used this and I have only just realised I am having problems with leap years. each time I get to February of a leap year my program stops, therefore I have attributed it to my code not accounting for leap years. Is there a simple way to fix my code (below) to account for leap years?</div>

<div>Thanks</div>

<div class="im"><br>while month < stop_month:<br> accumulate_month(month.year, month.month)<br> month += timedelta(days=32)<br></div> month = month.replace(day=01) </div>
