Have you ever seen a rain gauge?  

Your parents might have one in the yard or they probably used one when the weather of TV or radio reported how much it rained last night.  

Do they say it rained 3 years last night?

Thanks @mecharv and I hope my question didn't seem to be in anyway sarcastic to you @NeverlandsShadow. 

 Whether or not the amount of rainfall was over one day or even 19 years, the amount of rain is measured in inches or I guess feet, centimeters meters, etc....
