Count the number of consecutive occurrences

Hi,

I have an excel spreadsheet to record employee holiday and sickness figures.

It is set on as a grid e.g. column A stores all the dates and then employee names are used as column header.

One of the triggers I need to use is where, an employee has been absent 28 consecutive days. When an employee is absent I simply enter 'ABSENT' against there name.

Countif will count the number of time absent appears in the column however I need it to only recognise it if it is only 28 days in a row.

Any help would be much appreciated!

Thanks
