The time the House starts sitting each day is fixed. The time it finishes can vary according to the business. There is a usual time (known as the moment of interruption) at which the main business finishes and the half-hour adjournment debate starts, and then a usual time at which the sitting itself finishes, but you can't assume that these times will always apply.
If you're not sure what time a particular day's business is likely to finish you can ask the Table Office for advice.

The House usually meets at the times for a Monday sitting on the first day back after recess, whether this falls on a Monday or not.
