Unless otherwise specifically noted, a “day” refers to a calendar day and a document that must be filed by a certain date must either be postmarked on that date or received by the Docketing Clerk on that date. For documents that must be or are “filed” under these regulations, you count the number of days after filing starting with the day after the filing date as day one. For other time periods, you calculate the time period by counting the day after receipt by the party as day one. If the last day of a time period expires on a Saturday, a Sunday, or a Federal holiday, the last day of the time period will expire on the next business day.
