Purpose

Reference first, calculator second

The site is designed to make ordinal-date information easy to browse, not just to answer a single query. That is why it includes daily pages, month hubs, quarter hubs, methodology notes, and a downloadable dataset.

The intended audience includes engineers, analysts, operators, planners, and anyone who needs to translate between calendar dates and day-of-year values quickly.

Related Terminology

Ordinal dates and Julian dates

Many business systems casually call ordinal dates “Julian dates,” but that is not the same as the astronomical Julian Date system. ordinaldate.com focuses on ISO-style ordinal dates.

If you are specifically looking for the Julian Date concept and related explanations, see juliandatetoday.com.
