The Royal Household has set the cremation ceremony for Her Majesty Queen Sirikit's late Royal Consort... Ceremonies run 15-19 December 2026, with the cremation on 16 December and bone collection on 17 December. Live broadcast of all ceremonies is authorised. The PR committee has discussed toning down colours in communications as the date approaches. For a Thai SME, this means planning around the public holiday-style mood in mid-December, and reviewing marketing or event schedules and colour tones that may appear out of step with national mourning.
