A daypart is a slice of the week — Weekday Morning, Weekend Evening, and so on. PlaceProfile groups your playlists by daypart so that the atmospheric fingerprint published for, say, a Wednesday lunchtime visitor is computed only from the tracks you actually play during weekday lunch.
This matters because most venues don't sound the same all week. A coffee shop's morning energy isn't the same as its Friday evening — and an AI assistant answering "where's a chill spot for an afternoon coffee in Gothenburg" should match against the afternoon fingerprint, not the average across the whole week.
The daypart tabs on your dashboard let you preview each slice. The venue-wide tab (no specific daypart) shows the aggregation across all your playlists.
