Excels SUM, DATO, WEEKDAG, IF, Nested IF and IF / OR features came in mind when I watched a 1969 movie called * If it's Tuesday, this must be Belgium, * about American tourists on a whirlwind tour in Europe. It occurred to me that companies often have to create schedules based on the weeks (as opposed to the days) for a month – such as week1, week2, week3, etc. This would mean using a date formula to identify each week in a given month, plus a series of recent IF / OR rates to assign tasks and team members to complete these tasks. Using Excel as scheduling tools is a great skill to wear under your belt.

Imagine working for a magazine that covers sporting events all over the world, and it's your job to create schedules for journalists and videographers that cover these events. For example, on the third Tuesday of a certain month, the event is ice skating and the place is Belgium; The fourth Tuesday is the bobsledding in Scotland; The first Thursday there is golf in Ireland; and last Thursday it is rugby in New Zealand. The formulas below can make this difficult and time-consuming task a simple, quick and easy task.

We have included a downloadable spreadsheet that you can use to exert these skills:
