Determining Time Periods Expressed in Number of Days
If the time period is expressed as “at least” a certain number of days or as “clear days”:
You measure the time period counting the number of business days or “clear days” between two events, not including the first or last day. For example, three days before a Wednesday chambers date is the Thursday of the previous week (ie., you do not count the Thursday but count Friday, Monday and Tuesday (do not count Saturday or Sunday, as they are not business days or the Wednesday chambers date).
If the time period is expressed as “within” a certain number of days or simply as “days”:
You measure the time period by counting the number of days between two events, not including the first day but including the last day. For example, if a document must be filed 15 days after April 1st, it must be filed on or before April 16th (ie., you do not count the first day – April 1st – but you do count the last day – April 16th).
