when was the depression in Germany?

1930's The Great Depression, same everywhere else.

The depression in Germany got a bit of a head start on the rest of the world as a result of the conditions placed on it after WW1.

The Treaty of Versailles finalised WW1 and included arrangements that Germany would pay significant penalties to the victors including giving up valuable industrial regions and pay huge sums of money to France and Britain especially in reparation for war damage and loss.

As a result Germany's economy suffering great pressure and the fledgling Weimar Republic (Germany's government from end of WW1) had limited options.

Inflation took hold and crippled the economy as early as 1920.

Economic turndown and political instability saw the scene set for radical political parties including the NAZIs who ultimately took power in 1933.

How is this a military-theme question for christ's sakes?
