Summer and Winter Time - Calculator
A simple calculator, that converts from summer time (daylight saving) to winter time (normal time), or the other way. Please insert the time data into the first row.
In most countries with daylight saving, it is: summer time = winter time + 1 h. In central Europe, summer time is from the last Sunday in March to the last Sunday in October. In March, the clock jumps from 2 to 3 a.m. Sunday morning, in October it jumps from 3 to 2 a.m. on Sunday morning. Winter time is the normal time, even though summer time is for the longer part of the year.
