The answer

Day 144 of 2026 is Sunday, May 24, 2026. 2026 is an ordinary year with 365 days, so this date is 221 days before the end of the year. It sits in ISO week 21, in quarter 2, and is 130 days ago.

How the day number is found

Day numbers count from January 1, which is day 1. January has 31 days, so February 1 is day 32; in a common year March 1 is day 60, and in a leap year it is day 61 because February has 29 days. The table above lists the first and last day number of every month in 2026, so you can check any result by hand.

Ordinal dates in practice

Day-of-year numbers, sometimes called ordinal or Julian dates, are used in logistics, military and aviation records, satellite data, manufacturing lot codes and food packaging. The format YYYY-DDD, for example 2026-144, is part of the ISO 8601 standard. Note that the ‘Julian date’ used by astronomers is a different system.

Checking your answer

Take the last day number of the month before and add the day of the month: the previous month ends on day 120, and 24 more days gets you to day 144.

How the calendar works

The Gregorian calendar has twelve months of 28 to 31 days. A normal year has 365 days and a leap year has 366, with the extra day added to February in every year divisible by four except century years that are not divisible by 400. Because 365 is one more than 52 weeks, most dates move forward one weekday each year and two after a leap day. Weeks are numbered under ISO 8601, which starts weeks on Monday and gives week 1 to the week containing the first Thursday of January.
