1An outing with someone you are romantically involved with or interested in; a romantic appointment (often used with 'to date' in Japanese: デートする).
今度の日曜日に彼女と映画デートに行く予定だ。
I'm going on a movie date with my girlfriend this Sunday.
初デートは緊張するものだ。
A first date is something that makes you nervous.
付き合い始めてから毎週末デートしている。
We've been going on dates every weekend since we started dating.
2JMdict also lists a rarely-used sense of 'date' meaning a calendar date, but modern Japanese essentially never uses デート this way — 日付 is used instead.
