Exam dates are typically not mentioned in exam preparation books or study materials. These materials are designed to provide candidates with the necessary knowledge and skills to prepare for the exam, rather than providing specific details about the exam itself. However, there are several other reliable sources where candidates can find information about exam dates.

1. Official Exam Website:
The official website of the exam conducting authority or organization is the most reliable source for exam-related information, including exam dates. Candidates should regularly visit the official website to stay updated on any announcements or changes regarding the exam schedule.

2. Exam Notification:
Exam notifications are released by the conducting authority to provide detailed information about the exam, including important dates such as the start and end of the application process, exam dates, and result declaration dates. These notifications can be found on the official website, in newspapers, or through other communication channels.

3. Exam Calendar:
Many exam conducting authorities publish an annual exam calendar that provides a comprehensive schedule of upcoming exams. This calendar includes important dates such as application deadlines, exam dates, and result announcement dates. Candidates can refer to these calendars to plan their exam preparation accordingly.

4. Exam Preparation Apps:
There are several exam preparation apps available that provide comprehensive study materials, practice tests, and exam-related information. These apps often include exam schedules and notifications, allowing candidates to stay updated on the latest exam dates and other important information.

5. Coaching Institutes:
Candidates who are enrolled in coaching institutes for exam preparation can obtain information about exam dates from their respective institutes. Coaching institutes often have access to the latest updates and can guide candidates regarding exam schedules.

In conclusion, while exam preparation books and study materials may not mention specific exam dates, there are several reliable sources where candidates can find information about exam dates.
