We update the data in different schedules, so it’s hard to say exactly ‘when’ we update. For example, popular playlists with more than 50K followers are updated more frequently (00AM, 8AM, 16AM UTC), versus less popular ones (less number of followers) are updated once a day, or once in two days. All the charts are updated daily (unless they are weekly charts), and most of the artist stats (social media stats, Spotify followers, etc) are updated daily. Audience demographic data and 'affinity' scores update once per month or more.
