What is different about 2027

Every common year has the same day numbers: March 1 is always day 060 and December 31 always day 365. What changes from year to year is the weekday under each number. 2027 starts on a Friday (day 001) and ends on a Friday (day 365), so it has 53 Fridays and 52 of every other weekday. Its first Monday is day 004. The years with exactly the same calendar, weekdays included, are 2010, 2021, 2038, 2049: a chart printed for 2027 is valid for them too.

Dates set by weekday move. These are the day numbers that belong to 2027 alone:

Date	2027	Day	YYDDD	CYYDDD

Martin Luther King Jr. Day (third Monday of January)	Mon, January 18	018	27018	127018

2027 counted from today

January 1, 2027 (day 001): 59 days. December 31, 2027 (day 365): 423 days. Today’s own code is 6307 in YDDD form, and when today falls in 2027 its cell in the chart above is outlined.

Mainframe and ERP codes for 2027

Systems that need the century in a six-digit field, such as JD Edwards and other ERP and mainframe software, write CYYDDD: a century digit (0 for the 1900s, 1 for the 2000s), then YYDDD. In 2027 the codes run from 127001 to 127365; July 4 is 127185 and Christmas 127359. The same day in 1927 was 027359, which is why the century digit exists. The four-digit YDDD code used on some lot numbers keeps only the last digit of the year, so 7001 means January 1 of 2027, but also of 2017 and 2037: read it next to a production date.

Quarters of 2027 as day numbers

A lot code or shipping date often only needs the quarter. Q1 is days 001 to 090 (27001–27090), Q2 is 091 to 181, Q3 is 182 to 273 and Q4 is 274 to 365. The first Monday of 2027 is day 004, so a weekday count from a day number starts there.

Astronomical Julian Days in 2027

If you need the astronomers’ Julian Day rather than a day-of-year code: January 1, 2027 at 0h UT is JD 2461406.5 (MJD 61406), and December 31 at 0h UT is JD 2461770.5. Add the day number minus one to January 1’s value for any other date. The Julian Day Number in the table above is the one in force from noon UT of each date.

The Julian calendar in 2027

The Julian calendar runs 13 days behind ours throughout 2027, so its New Year’s Day, Julian January 1, 2027, falls on Gregorian January 14, 2027. A “Julian calendar 2027” in that historical sense is this year’s calendar shifted by 13 days; the chart above is the day-of-year chart that most people searching for a Julian calendar want.

Converting a code: split it into year and day, then look the day up in the chart. 27045 is day 45, February 14; 27304 is day 304, October 31. To convert any single code, including JD, MJD and CYYDDD, use the Julian date converter.
