How the deadline works

Under MCR 2.309(B)(4), the answers and objections to interrogatories is due within 28 days after service of the interrogatories. A defendant served with the interrogatories together with the summons and complaint has 42 days. A deadline landing on a weekend or court holiday moves to the next business day.
