WIPO Madrid Bureau Lists 8 Non-Working Days for 2027

WIPO published Madrid Information Notice No. 46/2026 on 9 November, listing the days in 2027 on which the International Bureau will not be open to the public: 8 days in addition to Saturdays and Sundays. The notice also reminds users that the International Bureau will be closed on Friday 25 December 2026 and Thursday 31 December 2026.

International Bureau non-working days in 2027

• 1 January (Friday): New Year
• 26 March (Friday) and 29 March (Monday): Easter
• 6 May (Thursday): Ascension
• 17 May (Monday): Whitsun and Eid al-Adha
• 2 August (Monday): Swiss National Day
• 24 December (Friday) and 31 December (Friday): Christmas Eve and New Year's Eve

When a deadline falls on a closed day

Under Rule 4(4) of the Regulations under the Madrid Protocol, a period that expires on a day when the International Bureau or the Office concerned is not open to the public expires on the first following day on which it is open. For example, a period before the International Bureau expiring on 31 December 2026 moves to Monday 4 January 2027: the International Bureau is closed that day, 1 January is New Year's Day and a weekend follows. Periods before a designated Office or the Office of origin follow that Office's own working days, not the International Bureau's list.

J&C notes: for Madrid deadlines around the year end and next year's holidays, first check who receives the filing. International applications and subsequent designations filed through CNIPA follow CNIPA's working days, so check them against China's official 2027 holiday schedule; only subsequent designations, renewals and replies to International Bureau communications filed directly with WIPO follow the list above. An extension only moves the expiry date, so it is still safer to file a few days early.
