While there’s no strict rule about when to hold a bucks party, it is traditionally celebrated in the days or weeks leading up to the wedding rather than the night before. Planning it too close to the wedding can lead to potential issues, such as hangovers or fatigue that might affect the groom’s big day. Many groups choose to have the bucks party a week or two prior to the wedding to allow ample recovery time. This timing also gives everyone a chance to reflect on the celebration and share any memorable moments during the wedding festivities. Ultimately, the timing should cater to the groom’s preferences and schedule.
