Julian Date Today

Need today's Julian date, a converter, or a year table? This page brings the major meanings together without mixing them up: the day-of-year code used in business systems, the astronomical Julian Date and Julian Day Number, and the corresponding date in the Julian calendar.

Julian Day Number

2461263

Julian Calendar Date

July 28, 2026

Ordinal results use your current local date. Astronomical JD and MJD use the current UTC-based instant. Those are intentionally different because the underlying systems are different.

Which Julian Date Do You Need?

Ordinal "Julian" date

2026222 / 26-222

Used in manufacturing, food packing, logistics, and many legacy systems. It means year plus day-of-year.

Julian Day Number

2461263

The integer astronomical day count. Useful when you need the day number but not the time-of-day fraction.

Julian Date (JD)

2461262.95269

The continuous astronomical day count in UTC. It includes fractional days and changes throughout the day.

Julian calendar date

July 28, 2026

The older civil calendar date corresponding to today's Gregorian date.

Why This Term Confuses People

The phrase Julian date is used loosely on the web. Sometimes it means a simple year-and-day code such as 2026161. Sometimes it means the astronomical Julian Date near 2461202.xxxxx. In other cases, people are really asking about the old Julian calendar itself.

That overlap is why so many search results feel incomplete. This page keeps the meanings separate, gives you the right converter for each one, and puts the practical answer near the top instead of hiding it under a long explanation.

Converters

Calendar Date to Julian Formats

Start with a normal calendar date and see the matching ordinal code, JDN, and Julian-calendar date.

Ordinal Julian Date to Calendar Date

Use this for packaging codes, manufacturing labels, mainframe exports, or any yyddd / yyyyddd value.

Accepts yyyyddd, yyddd, yyyy-ddd, or yy-ddd. Two-digit years are interpreted as 2000-2099 on this page.

Astronomical JD / JDN / MJD Converter

Use this when you need the scientific format rather than a business day-of-year code.

JD includes fractional days. JDN is the integer day count. MJD is just JD - 2400000.5.

Where Each Format Is Used

Food and product labels

Most packaging codes that people call Julian dates are really ordinal dates such as 26-161. You need year plus day-of-year, not astronomical JD.

Astronomy and scientific software

Astronomical tools usually want JD, JDN, or MJD in UTC because those formats avoid month-name ambiguity and make time intervals easier to compute.

Historical or church-calendar references

If the question is about the Julian calendar itself, the useful answer is the old-calendar date and the difference from the Gregorian date, not a yyddd code.

Julian Date Calendar Table

This is the day-of-year lookup table most people want when they need a quick annual reference. Each cell shows the three-digit day number for that month and day, and leap-year tables include day 366 automatically.

How to Read Julian Date Codes

A code such as 2026161 means the 161st day of 2026. That is June 10, 2026. The shorter form 26-161 means the same thing with a two-digit year. This format is common on food packaging, manufacturing labels, batch records, and older business systems.

The astronomical Julian Date is completely different. A value such as 2461202.5 is not a year-and-day code. It is a continuous day count measured from a very old epoch, and the decimal fraction encodes the time of day in UTC.

The Julian calendar is different again. It is an older calendar system with a simpler leap-year rule than the Gregorian calendar. For modern dates it is currently 13 days behind the Gregorian calendar.
