Why dont you go by the postmarked date for a motion to set-aside the default filing deadline?
The motion to set-side the default filing deadline is set by ordinance. According to the Chicago Municipal code section 2-14-108, an Administrative Law Officer may set aside any order entered by default and, if granted, set a new hearing upon a motion filed within 21 days after the issue of the default order. The Department of Administrative Hearings counts the 21 days from the date the default order was deposited in the U.S.
