Depending on your case, you can let the journey run daily and have one of the following time filtering options specified in the Conditions activity (https://experienceleague.adobe.com/en/docs/journey-optimizer/using/orchestrate-journeys/about-journe...) along with additional conditional checks to confirm if its the second Thursday of each month
Day of the week: allows you to set up a condition based on the day of the week. You then select which days you want individuals to enter the path.
Day of the week and hour: allows to set up a condition based on both the day of the week and the time (start-end hours)
