The Pennsylvania General Assembly is comprised of a 203 member State House and 50 member State Senate. The House and Senate convene for a two-year session on the first Tuesday after New Year's in the odd year and adjourn finally (also called adjourning Sine Die) on Nov. 30 of the even year.
The House and Senate convene in Harrisburg on legislative session days, generally Mondays-Wednesday of weeks that have been scheduled for legislative session.
When the House and Senate are in voting session, they each follow a calendar to consider bills.
The legislative process can be a complicated one, but this guide from the PA House of Representatives provides a good review of how a bill becomes a law.
