How to keep pandit on schedule during ceremony?

Context before I start: this is a multicultural wedding happening in the US!

Our pandit mutually agreed with us to a 40-45 minute long Hindu ceremony. We have other short elements to our wedding ceremony and want to stay within an hour/hour and 10 minutes. If we’re over by 5-10 minutes that’s totally fine, but where I worry is if we’re starting to approach 20-30+ minutes over time. We need to have time for everyone to change, flip the venue for the reception, etc.

Last week we talked with our pandit and laid out our ceremony schedule with each ritual we will include. He also suggested that we put English translations of some mantras into our printed program instead of him translating out loud to save time. So overall, it seems he’s very committed to staying on schedule.

However, I know that in the heat of the moment, some pandits get very passionate and want to continue talking. Our pandit is very heartfelt and got somewhat long-winded when we met with him. He does lots of different events and speaking engagements, both Hindu and multicultural, so I have faith he will stay on schedule, but I still want to plan ahead.

Do you have any recommendations for a respectful way to make sure the pandit doesn’t go too far over time? I don’t want to interrupt or anything and of course I want to enjoy my own ceremony and be in the moment. Maybe there’s something we can establish with him ahead of time, like a signal or moments in the program to do a time check? My mom will be under the mandap and she has been talking to our pandit too; maybe I could designate her to communicate with him during the ceremony and keep track of the time?

Thanks in advance for suggestions!
