How Many Days are the Guide?

A simple question but I’m used to 21 days of guide data with WMC with epg123 yet it seems that Plex’s guide is considerably shorter. How many days out does it go? Is there any way to get more days?

TIA

In general terms,(U.S.?) guide data usually goes out 10 to 14 days. For example., https://tvlistings.zap2it.com/?aid=gapzap and http://www.tvguide.com/listings/ each go out 12 days.

Is it possible to use our Schedules Direct (US) account to get more days? There’s no place to put in the creds on the Plex Sever.
