Using で to mark location with ある?


My understanding is that the verb ある describes where something **is** , which
means に is the correct particle to mark location. However there have been
several cases I've come across where ある's location actually uses で:

> (Requesting vacation time from a boss) あの、実は来月、私の国 **で** 姉の結婚式がありまして...

> 日本 **で** はよくある - be common in Japan

I know I've seen more, but I'm struggling to find more at the moment. If more
examples would help let me know.

Is this related to how we mark location with で [in noun/adjective
sentences](https://japanese.stackexchange.com/a/21496/4382) somehow?




ある usually describes a (long-term) existence, but ある sometimes means "(for an
event) to happen; to be held". In such cases, you have to use not に but で just
like other action verbs. よく ("commonly", "often") is an adverb that clearly
indicates the following ある means "to happen".

Examples (use of に is incorrect):

  * 明日デパート **で** セールがある。  
There will be a sale at the department store tomorrow.

  * この企画について昨日の会議 **で** 決定があった。  
A decision about this project was made at yesterday's meeting.
