An event occurring every two years is referred to as a biennial event. This pattern indicates that the event happens once every two years.
Every fourth day refers to a specific pattern of time intervals where an event or occurrence takes place every four days. For example, if an event happens on a Monday, it would also occur on the following Thursday, then the next Sunday, and so on, continuing this cycle. This pattern can be used for scheduling activities or tracking events over time.
