"I am a traditional guy. I have lived in this drafty castle since 1893, and honestly, I haven't seen a decent tailor for centuries. I usually wake up at midnight, so I'm definitely a night owl."

Romance languages often use the same preposition (like desde) for both starting points and durations. English splits them up!

• Use since for a specific starting point in time (since 1893, since Tuesday).

• Use for for a duration or length of time (for centuries, for two weeks).

• Use at for specific clock times or precise moments (at midnight, at 3:00 PM).
