About Sprinklertime

Sprinklertime is a free, independent website for the sprinkler runtime and catch-can calculator.. The calculator runs in your browser and uses the dimensions and assumptions you enter. It does not require an account or payment.

The guide explains the arithmetic, worked examples and limits. Verify dimensions and any product-specific inputs before purchasing materials. The tool is part of the same operator portfolio as Seedcount and shares its support inbox.
