Cultural Tip
German speakers prefer precise time references. If you are unsure about the exact moment, you can soften the question with 'ungefähr' (approximately) or ask for a range, e.g., 'Um wie viel Uhr hat das Problem angefangen?'. In formal settings, you might also use the more formal 'Wie ist das Problem entstanden?'.
