Viertel sieben
... German for => a quarter past six (time of the day)
In German "viertel sechs" and "viertel vor sechs" must not be confused. The first version means: a quarter on the way from six to seven o'clock, which is either 6.15 or 18.15. The latter means: a quarter still before us on the way from six to seven o'clock, which can either mean 6.45 or 18.45.
