No, specific dates like years or months are not explicitly mentioned in the Quran.
The Quran focuses on delivering God's message and guidance for all times and places. It is not a historical document that aims to provide specific dates for events.
However, the Quran does mention certain events and their chronological order, which can be used to deduce the approximate timeframe of their occurrence.
For example, the Quran describes the Prophet Muhammad's (peace be upon him) journey to Jerusalem, known as the Isra and Miraj, which is believed to have taken place in the year 621 CE. This event provides a reference point for understanding the chronology of other events mentioned in the Quran.
Overall, while the Quran doesn't provide specific dates, it does offer insights into the chronological order of events and their significance.
