Month (avg) to Day Converter

Convert months to days instantly. Free, bidirectional, and fully in-browser.

1 month (avg) equals 30.4375 days — enter any month (avg) value to convert it to days instantly. This Month (avg) to Day converter is a client-side tool: it applies a single multiplication (d = mo × 30.4375) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert days back to months. A reference table lists common month (avg) values already converted, and nothing you enter is sent to a server.
