What does Julian date mean?
“Julian date” names two different things, so check which one a form or system wants.
- Ordinal date (YYDDD or YYYYDDD). The military, food and drug manufacturers and many shipping and mainframe systems write the two-digit (or four-digit) year followed by the day of the year with three digits. December 31, 2028 is 28366 or 2028366. This is a day-of-year count, not a Julian-calendar date.
- Astronomical Julian Day (JD). Astronomers count days from noon on January 1, 4713 BC in the Julian calendar. The Julian Day Number of a calendar date is the integer JD at noon that day: January 1, 2000 is 2451545. A JD at midnight ends in .5, so the JD of a moment is a number with a fraction. Unix time (seconds since January 1, 1970 UTC) is a third, unrelated count.
ISO week number rules
ISO 8601 weeks start on Monday, and week 1 is the week that contains the year's first Thursday (equivalently, the week with January 4). A year has 52 or 53 weeks, and the first or last days of a year can fall in a week of the neighboring year: for example, Friday, January 1, 2027 is in week 53 of 2026. Calendars in the U.S. often start the week on Sunday and number it differently.
Leap year rule
A year is a leap year when it is divisible by 4, except century years, which must also be divisible by 400. So 2028 and 2000 are leap years and 1900 and 2100 are not. A leap year has 366 days, with February 29 as day 060, and every later date is one day higher than in a common year.
Day of the year table, 2026 to 2028
The day of the year on which each month starts, in the three-digit form used in YYDDD dates. 2028 is a leap year.

Frequently asked questions
What is today's Julian date?
It depends on which Julian date you mean, and the page shows both for your local date when it loads. The ordinal Julian date used by the military and manufacturers is the two-digit year followed by the day of the year with three digits (YYDDD), or four-digit year plus day (YYYYDDD): December 31, 2028 is 28366 or 2028366. The astronomical Julian Day Number counts days since noon on January 1, 4713 BC in the Julian calendar, and January 1, 2000 is 2451545. This page does not print a fixed value because the answer changes every day.
What week number is it?
The page shows the ISO 8601 week number for your local date. ISO weeks start on Monday, and week 1 is the week that contains the year's first Thursday, so the first days of January can belong to week 52 or 53 of the previous year, and the last days of December to week 1 of the next. Other systems number weeks differently, for example starting on Sunday, so a calendar or payroll system may show another number.
How many days are left in the year?
Days left in the year is 365 minus the day of the year, or 366 minus it in a leap year, so the last day of the year has 0 days left. The page shows this number for your local date. Whether today counts as one of the days left is a matter of convention; this page does not count today.
What day of the year is it?
Day of the year counts from January 1 as day 1 to December 31 as day 365, or 366 in a leap year. The page shows it for your local date and in the table below you can see the day number on which each month starts.
