Schedule?

Yesterday, I was sitting next to dear hubby in the car when he took a work call. No worries, I was driving...yes you read that right, no need to adjust your computer. I do drive here, actually, I drive here every day . I just don't LIKE to. It is just really unnatural sitting on the passenger side of the car to drive. But I digress...I hear him talking and then towards the end of the call he says, "I will check my diary, but my schedule is open". A diary is what they call their calendar or planner, so I got that. Only...he did not say schedule like we Americans say schedule. No, my dear hubby said it the way British people say it --which sounds more like shhedduel. I looked at him and said --"did you just say shhedduel?????" He just looked at me and said, "why yes, yes I did." Hmmmmm.
