Columbus Day is one of those stealth federal holidays that does not get the attention of Memorial Day or Labor Day. It is relevant for those of us practicing Social Security disability law in the Region 1 (the New England states), because we have a 5-day rule for new evidence.
The 5 days excludes weekends and holidays. So if you have a hearing during the week following Columbus Day, you must take the holiday into account when figuring the deadline for new evidence.
Our office will be closed for the holiday. But our evidence for the upcoming cases has already been filed.
