German winter and summer time

[Boris Ciglic]

Hello gents,

What were the exact dates throughout the war when the Germans switched from summer to winter time and vice versa.

Cheers,
Boris

You can thank Steve Coates for the following, which I've found incredibly useful over the years:

The Germans used CET (Central European Time, which they called MEZ = »mitteleuropäische Zeit«) and GST (German Summer Time)

CET = GMT + 1 hour
GST = GMT + 2 hours

German time varied as follows:–

To

1/4/40 - CET

From

1/4/40 - GST
2/11/42 - CET
29/3/43 - GST
4/10/43 - CET
3/4/44 - GST
2/10/44 - CET
2/4/45 - GST
18/11/45- CET

Very useful information, Nick! Thank you and Steve. Do you happen to have the same for any of the other combatant nations?

[Chris Goss]

These changes normally came into effect at 0200 hrs, same with the British. I have times for UK which changed 14 times during the war (at 0200 hrs)

[Paul Thompson]

Thank you, Chris. Why did the British change times more frequently? Your email is still the tinyworld one, I assume.

[Chris Goss]

I guess to make the most of daylight? Yes the email is the same plus I now have a @gmail.com with the same prefix

[Boris Ciglic]

Thanks a lot Chris!

...and don't forget Nick!

During the war, local time in the UK varied from GMT(Greenwich mean Time) to BST (British Summer Time) to BDST (British Double Summer Time): BST = GMT + 1 hour; BDST = GMT + 2 hours.

16/4/39 - BST
