When was the battle of jutland?

At 14:20 on 31 May, scouts from Beatty's force reported enemy ships to the south-east: British light units, investigating a neutral Danish steamer which was sailing between the two fleets, found German scouts engaged in the same mission. Beatty moved to cut the German ships off from their base. The first shots of the battle were fired when Galatea of the British 1st Light Cruiser Squadron mistook two German destroyers for cruisers and engaged them. Galatea was subsequently hit at extreme range by her German counterpart, Elbing, of Rear Admiral Bodicker's Scouting Group II.
