Hi All

I am a first time member to the forum! I am also very limited in my excel expertise. I have been using excel to create a work schedule with start times and finish times for multiple contracted jobs on any given day over a working fortnight. The problem is that while the duration at each job is unchanged, sometimes due to seasonal changes i need to shift all jobs by anywhere between 30 minutes or 2 hours. Any help would be much appreciated
