다니까

I'm telling you; since they say

Repeats something you have already said, with the impatience of not being believed: I'm telling you it's great, it's way more refreshing than you'd think. Inside a sentence it gives the reason instead, meaning 'since it is said that' — since 1 a.m. is lucky, just use that; since you can only see them now, people go out of their way. It attaches to descriptions and past forms; ㄴ다니까 covers present-tense action verbs and 라니까 covers nouns.

Register: casual, insistent
