I asked coplite and it give me the below flow. Does any one knows if this would work? Because I don't think I will know the answer until there's a holiday on a Tuesday. so, I can't figure it out in a short time. this flow ensures that a weekly email is sent every Tuesday morning at 8:00 AM Eastern Time, but if the scheduled day is a holiday, the email will be delayed by one day.
Delay until code:addDays(triggerOutputs()?['start'],1)
