The length of Congressional sessions varies from year to year. In the past decade the Senate has been in session for an average of 162 days, and the House of Representatives has been in session for an average of 142 days.
Third session of Indina National Congress
In the US, a Congress convenes every 2 years, in January. It could be over in 3 days, if they got all their work done, or it can take them almost the whole two years until the next Congress begins.
No more than 3 days without the consent of the other house. Article I, Section 5 of the US Constitution states: "Neither House, during the Session of Congress, shall, without the consent of the other, adjourn for more than three days, nor to any other Place than that in which the to Houses shall be sitting."
If not in session, the governor has 20 calender days to take action. If he does not meet this deadline, the bill becomes law. If it is vetoed, it is dead until the next session.
Looks like about 190 days. http://thomas.loc.gov/home/ds/s1101.html That means they weren't in session for about 175 days.
When a president opposes a bill, he may try to stop it from becoming law by vetoing it. Many vetoes are immediate, but he has a ten-day period during which he can do it. When congress is in session, and the president vetoes a bill, the proposed bill can then goes back to congress, which can try to over-ride the president's veto. This requires a 2/3 majority in both houses of congress. Sometimes a president can stop a bill another way. If congress is not in session, he can simply do nothing for ten days, which is called a "pocket veto," and the bill will not become law, because congress is not in session to try to over-ride it.
In the current session which is about to end there are 53 which is a majority for the Democratic Party.
There were 31 days in May 2013.
184 days
In 2013, there were 365 days as it was not a leap year.
