What does the fixed interval option do?

The fixed interval option can be selected when you create a:

• maintenance task.
• safety drill.

The following table clarifies what this option does.

A task or a drill has an interval of one month.

	No fixed interval	Fixed interval
Expiration date	1 January	1 January
Date of first execution	3 January	3 January
Next expiration date	3 February	1 February
Date of second execution	6 February	6 February
Next expiration date	6 March	1 March

With a fixed interval, the next expiration date is always calculated from the first expiration date.
