@spicecravings There's no great way to see this in Pinterest analytics. Since Pinterest is a search and discovery platform - time of day to post is not as important as it is on platforms like IG and TikTok.
I would just pin sometime in the morning, around lunchtime, and before/after dinnertime. But you also have different time zones so again, it doesn't really hold a lot of weight to pin at the "perfect" time. Hopefully, that makes sense!
