CALCULATION OF TIME LIMITS
Pursuant to Article 29 of the UNAT Rules of Procedure (Rules), time limits:
(a) Refer to calendar days, but do not include the day of the event from which the period runs;
(b) Include the next working day of the Registry when the last day of the period is not a working day;
(c) Are deemed to have been met if the documents in question were dispatched by reasonable means on the last day of the period.
For example, if you receive a UNDT judgment on 7 March 2018 and you want to appeal that judgment, the 60-day time limit will start to run on the day after your receipt of the UNDT judgment, i.e., 8 March, and will end on 6 May. Since 6 May is a Sunday, you may file your appeal on Monday, 7 May 2018.
