The future event starts at 14:45 hours. The information given states that the future planning session is scheduled to begin at 14:45 next week. This time is provided directly and unambiguously in the passage. Therefore, based solely on the details presented here, we can definitively say that the future event commences at 14:45 hours in 24-hour time format. The other time references like the rescheduled meeting yesterday and the meeting and lunch break tomorrow are not relevant to determining the start time of the future planning session which is the specific question asked. Providing a different start time for the future event would contradict the information clearly stated in the passage. I hope this answers your query! Let me know if you need any clarification.
