How many rainbows are seen per year?

The number of rainbows seen per year varies greatly depending on factors like geographical location, weather patterns, and the observer's vantage point. In regions with frequent rain and sunshine, such as tropical areas, rainbows can be seen multiple times a week. Conversely, in drier or less sunny regions, rainbows may be a rare occurrence. Overall, it's difficult to quantify an exact number of rainbows seen globally each year.
