Kan. Admin. Regs. § 44-15-101b
Grievances shall be filed within 15 days from the date of the discovery of the event giving rise to the grievance, excluding Saturdays, Sundays and holidays. No grievance, regardless of time of discovery, shall be filed later than one year after the event. Any grievance filed later than these deadlines may be returned to the inmate without investigation. The name of the individual returning the grievance, the date of the return, and the reasons for the return shall be noted on the grievance. An inmate may move to the next stage of the grievance procedure if a timely response is not received at any step in the grievance process, unless an extension of time for the response is agreed to in writing by the inmate and staff person answering the grievance.
