Moon Phase Calculator
Moon Phase Calculator is a everyday life calculator that helps you calculate pH or pOH from ion concentrations. The formula used is: Moon age = (date − reference new moon) mod 29.53 days; illumination = (1 − cos(2π × age/29.53)) ÷ 2. Enter values using the units shown next to each input. Common units such as litres, kg, and minutes are labelled.
