The best man acts as the groom's right-hand man throughout the wedding process, offering support and handling a variety of tasks. Here's a breakdown of his typical duties:

Before the Wedding Day:

Planning and Support: This can involve helping choose the groom's attire, organizing the bachelor party (if having one), and sometimes even assisting with guest list management or travel arrangements.
Moral Support: The best man is there to lend an ear, offer advice, and generally keep the groom calm and collected during the planning stages.

The Rings: He's entrusted with safeguarding the wedding rings until the ceremony.

On the Wedding Day:
Groom's Right-Hand Man: He ensures the groom is dressed, fed, and on schedule.
Groomsmen Management: The best man keeps the groomsmen organized and informed about the day's agenda.

Ceremony Participation: He typically stands beside the groom during the ceremony.

Reception Duties:
The Speech: A major responsibility is delivering a heartfelt and entertaining best man speech, often sharing funny anecdotes or stories about the groom. When the best man toast will be made, make sure you discuss before hand with the DJ and/or host. This announcement will help with timing and the flow of the speech.

Party Atmosphere: The best man might help keep the reception lively by dancing with the maid of honor and mingling with guests.

Overall, the best man's role is to ensure the groom has a smooth and enjoyable wedding experience. He should be dependable, organized, and willing to go the extra mile to make the groom's special day a success!
