 disfluent question: When are I mean where do plenary meetings take place? 
 context: Parliament typically sits Tuesdays, Wednesdays and Thursdays from early January to late June and from early September to mid December, with two-week recesses in April and October. Plenary meetings in the debating chamber usually take place on Wednesday afternoons from 2 pm to 6 pm and on Thursdays from 9:15 am to 6 pm. Chamber debates and committee meetings are open to the public. Entry is free, but booking in advance is recommended due to limited space. Meetings are broadcast on the Parliament's own channel Holyrood.tv and on the BBC's parliamentary channel BBC Parliament. Proceedings are also recorded in text form, in print and online, in the Official Report, which is the substantially verbatim transcript of parliamentary debates.
Output:
