Federal law and regulations provide a period within which an action is required for
a number of situations (e.g., the date on which a Modification must be delivered).
SSA considers the period of limitation to end at the close of the calendar day established
by the underlying rule. If the period ends on a Saturday, Sunday, legal holiday, or
any other Federal non-work day, action taken on the next Federal business day will
be deemed to be within the time limitation.
NOTE SSA considers the close of the calendar day to occur at 12:00 am as determined by
the State’s time zone, and in accordance with the relevant State’s rules relating
to daylight saving time.
