(a) In computing any period of time prescribed or allowed by these regulations, the day of the act or event from which the designated period of time begins to run is not included. The period of time begins to run the next day after the day of the act or event. The last day of the period so computed is included unless it is a Saturday, Sunday, or legal Federal holiday, in which event the period runs until the end of the next day that is neither a Saturday, Sunday, nor a legal Federal holiday, unless otherwise provided by this part or by the terms of an FE order. Documents received after the regular business hours of 8 a.m. to 4:30 p.m. are deemed filed on the next regular business day.
(b) When a document is required to be filed with FE within a prescribed time, an extension of time to file may be granted for good cause shown.
(c) An order is issued and effective when date stamped after the order has been signed unless another effective date is specified in the order.
