The measure was confirmed by the Ministry of Social Affairs, reported Austria’s Der Standard newspaper early on Tuesday.
The measure will apply from Wednesday, November 11th, until November 22nd.
This does not apply to petrol stations, ticket offices at train stations or to airports.
“This restriction of the opening times is intended to ensure that purchases are made in good time before the start of the exit restriction, so that the ordinance's goal of the greatest possible reduction in mobility in the evening and night hours can be taken into account as best as possible,” the ministry said in a broadcast.
“The aim of this regulation is therefore to support compliance with the exit restrictions and thus to achieve a further reduction in all unnecessary social contacts.”
The tightening of the opening hours comes one week after Austria put in place sweeping new shutdown measures to curb the spread of coronavirus.
The centrepiece of the shutdown – a nightly curfew from 8pm to 6am – will remain in force from the same times.
Under the previous rules, shops were allowed to remain open to 8pm.
