The Scottish Government has decreed that the flag of Scotland will fly on all its buildings every day from 8 am until sunset. An exception is made for "national days". On these days, the Saltire shall be lowered and replaced with the Union Flag. These days are the same as the flag days of the United Kingdom with the exception of 3 September (Merchant Navy Day), which is a specific flag day in Scotland and during which the Red Ensign may also be used.
