Daylight saving time 2019 starts on 31st March!
Remember: Clocks will be set forward 1 hour (from 2 a-m. to 3 a.m.) in Austria and most countries in Europe. In local time, sunrise and sunset will be about 1 hour later on Sunday, March 31, 2019 than the day before, resulting in more daylight in the evening.
And here you have an aid in remembering what happens regarding time change:
"Spring forward, fall back."
