Julian date calendar charts by year.
Use the year pages when you need a scan-friendly lookup table instead of a one-off conversion. Every chart shows the Gregorian date, ordinal code, short production code, weekday, and quarter context.
Julian Date
Understand the difference between ordinal Julian formats and astronomical Julian day numbers, convert between formats, and browse reference charts by year.
Available year charts
Start with the current year, then move to adjacent years if you are working on archive, labeling, or planning tasks.
When a year chart is better than a converter
A converter is best when you have one date in front of you. A year chart is better when you are reviewing batches, reconciling records, printing a reference sheet, or checking multiple dates in sequence. Keep the year and all leading zeros when copying a code from the chart.
