three days and two nights, a two-night trip
A trip or stay lasting two nights and three days. A very common way to describe trip duration in Japanese, counting nights stayed rather than just days.

二泊三日 is composed of 二泊 (two nights' stay) + 三日 (three days).
PATTERN: The format X泊Y日 is the standard way to express trip duration in Japanese:
- 一泊二日: one night, two days
- 二泊三日: two nights, three days
- 三泊四日: three nights, four days
The number of nights is always one less than the number of days.
USAGE: This is the most common format for describing trip length in Japan. It appears in travel brochures, hotel bookings, and everyday conversation. 二泊三日 is perhaps the most popular duration for domestic weekend trips.
