I needs a formula (not VBA) to calculate the required start date.
I have to do a job of 14 working hours and this job must be finished on 05-may-2014 13:00
My working week is from monday u/i friday and every day I work from 08:00-16:00
At what time do I have to start the job to get it done in time.
The formula should give this result: 01-may-2014 15:00

I hope somebody can help me.
