Hi Balder and welcome!
I’m guessing it would be useful for you to have the weekly schedule of a JW who is roughly your age? If so...
Presently they have two meetings per week which you absolutely must attend. The Sunday one includes a public talk followed by the watchtower study (Watchtower and Awake are the two magazines published by the watchtower bible and tract society who essentially run the Jehovah’s Witness organisation. You are expected to read both magazines).
The midweek meeting is called our Christian life and ministry and is essentially a session given over to perfecting your ministry or preaching work.
Most families have a family Worship session usually on Fridays and will go out in the preaching work for a few hours on a Saturday. This is the minimum requirement for any baptised Jehovah’s Witness, known as a ‘publisher’. If you were to do less than this you would be known as ‘bad association’.
Young Jehovah’s witnesses are discouraged from pursuing further education and any hobbies or after school activities that are likely to take them away from the preaching work.
Jehovahs witnesses are also discouraged from befriending non-Jehovah’s witnesses, known as ‘worldly people’ because those considered part of the world are seen as being under the influence of Satan the devil.
Jehovahs witnesses believe the bible is the literal word of god and that their religion is the only true religion. They also have many rules they must abide by, which are stated in the watchtower magazine. Despite the fact JWs claim they live by bible standards, Many of these rules are not found in the bible - such as the no beards rule and the ban on higher education and the no voting in elections rule.
Academics and experts consider the Jehovah’s Witnesses as a cult, and indeed they fit the B.i.T.E. Model of a cult (which is worth looking up).
