に — time & destination
The "pin" particle: it fixes an action to a point in time or an endpoint in space — and it's the one you weigh against へ for "to".
The short version
に marks a specific point. Two of its jobs cover most of N5: a point in time ("at 7", "on Sunday") and the destination or endpoint a movement arrives at ("go to home", "be in the room").
A point in time
Attach に to a clock time, a day, or a date to say when. (Vague time words like 今日 "today" or 明日 "tomorrow" take no に.)
A destination or endpoint
With verbs of motion (行く go, 来る come, 帰る return), に marks where you end up. With existence (いる/ある) it marks where something is.
に vs へ — both mean "to"
For destinations, へ (pronounced "e") is often interchangeable with に. The nuance: に pins the exact arrival point, while へ stresses the direction you're heading. In everyday speech either is fine for "going to a place".
