To determine the approximate timespan of the book of Acts in the Bible, we can examine the text and historical context. The book of Acts, also known as the Acts of the Apostles, is believed to have been written by Luke, who was a companion of the apostle Paul.

In the book of Acts, the narrative follows the spread of Christianity after the death and resurrection of Jesus Christ, focusing primarily on the ministry of the apostles Peter and Paul. It also includes other significant events in the early Christian church, such as the Day of Pentecost and the conversion of Paul.

Based on the information provided in Acts and other biblical texts, as well as historical references from the first century, scholars estimate that the events described in Acts span a period of about 30 to 35 years. The book begins around 33 AD with the ascension of Jesus and ends around 68 AD, before the death of the apostle Paul.

To arrive at this estimate, scholars consider various factors, including the ministry of the apostles, the historical context of the Roman Empire, the reigns of different rulers mentioned in Acts, and the details provided regarding specific events and journeys.

It is important to note that the dating of biblical texts can be complex and there may be different interpretations among scholars. Nonetheless, the approximate timespan of Acts can be determined by studying the historical and textual evidence available.
