No biblical scholar here, but from what little I've read, I believe you are correct.
IIRC, there's a tale of two prophets called to heaven after 3.5 weeks.
If you read Revelation this is no time period of 7 years mentioned. A very good book on the subject is
THE SEVENTY WEEKS PROPHECY
An Exposition of Daniel 9
