How Many Days Are Left in the Year? The Formula, Plus the Count From Oct. 30, 2026

From Friday, Oct. 30, 2026, there are 62 days left in the year if you do not count today and 63 if you do, using the 365-day common year and the leap-year rule published by the U.S. Naval Observatory (USNO). The method works on any date: subtract today’s day number from the number of days in the year. This story shows the formula, the Oct. 30 example, a table for the first of every month in 2026 and in leap year 2028, and a one-page printable of that table.

What is the count of days left from Oct. 30, 2026?

Oct. 30, 2026 is day 303 of the year: 31 days in January, 28 in February, 31 in March, 30 in April, 31 in May, 30 in June, 31 in July, 31 in August and 30 in September add up to 273, and October adds 30 more. 2026 is a common year, so it has 365 days.

Count	Calculation	Result
Days left, not counting today	365 - 303	62 days (Oct. 31 to Dec. 31)
Days left, counting today	365 - 303 + 1	63 days (Oct. 30 to Dec. 31)
Weekdays in the 62 days	Monday to Friday, holidays not removed	44
Weekend days in the 62 days	9 Saturdays and 9 Sundays	18
Weeks in the 62 days	62 / 7	8 weeks and 6 days

Oct. 30 is a Friday, so counting today adds one more weekday (45 weekdays and 18 weekend days in 63 days) and makes the total exactly 9 weeks. These numbers are for Oct. 30 only; the number changes by one every day, which is why the page gives the method instead of a figure that goes stale. For what falls inside that stretch, see our December 2026 holidays and key dates story.

How do you calculate the days remaining in a year?

Three steps cover every date.

1. Find the day number: the count of days from Jan. 1 (day 1) up to and including today. Our guide on how to calculate the day of the year shows three ways to get it.
2. Use 365 for a common year or 366 for a leap year. The USNO states the leap-year rule this way: years evenly divisible by 4 are leap years, with the exception of centurial years that are not evenly divisible by 400. Its examples: 1600, 2000 and 2400 are leap years; 1700, 1800, 1900 and 2100 are not.
3. Subtract. For days left not counting today, take the days in the year minus the day number. For days left counting today, add 1.

In a spreadsheet, put the date in cell A1. Our formula for the day number uses the date function (DATE) and the year function (YEAR): =A1-DATE(YEAR(A1),1,0). Microsoft Support documents that a day value below 1 counts back from the first of the month, so a day of 0 is the last day of the prior month. For days left, the days-between function (DAYS) works: =DAYS(DATE(YEAR(A1),12,31),A1) returns the difference between Dec. 31 and A1. Microsoft Support describes its days function as returning “the number of days between two dates”, with 31-Dec-2021 minus 1-Jan-2021 giving 364, so it is a difference and does not count both ends. Add 1 to count today. For A1 = Oct. 30, 2026 the formula returns 62.

Does a leap year change the days left?

Yes, for dates before March 1. A leap year adds Feb. 29, so every date from March 1 on has a day number 1 higher than in a common year, while the days left after that date stay the same. January and February dates have one more day left in a leap year, because Feb. 29 is still ahead.

The table uses 2026 (common) and 2028 (leap). “Left” means days left after that date, not counting it; add 1 to count the date itself. Day numbers and counts are our computation from the month lengths and the USNO rule, checked two ways.

Date	2026 day no.	2026 left	2028 day no.	2028 left
Jan. 1	1	364	1	365
Feb. 1	32	333	32	334
Mar. 1	60	305	61	305
Apr. 1	91	274	92	274
May 1	121	244	122	244
June 1	152	213	153	213
July 1	182	183	183	183
Aug. 1	213	152	214	152
Sept. 1	244	121	245	121
Oct. 1	274	91	275	91
Nov. 1	305	60	306	60
Dec. 1	335	30	336	30
Dec. 31	365	0	366	0

Our leap year explainer covers the rule in full. The same table works for other years: use the 2026 column for any common year and the 2028 column for any leap year.

How do days left convert to weeks and months?

Divide by 7 for weeks and keep the remainder as days: 62 days is 8 weeks and 6 days. Months do not convert cleanly, because they run 28 to 31 days; from Oct. 30 the days left cover all of November (30 days) and all of December (31 days), plus Oct. 31. The full weeks in a year are a separate question, covered in how many weeks are in a year.

The count above is calendar days, weekends included. A working-days count removes weekends and, depending on the employer, holidays. The 44 weekdays from Oct. 31 to Dec. 31 still include Thanksgiving, Christmas and any other weekday holiday, so use it as a ceiling, not as a count of days worked. Our business days for November and December 2026 story lists working days for that period.

How do you set up a year-end countdown?

A countdown is a personal planning tool, not an official calendar of holidays or work days.

1. Pick the target date. Dec. 31 gives the days left in the year; any other date (a deadline, a trip) gives a countdown to that date using the same subtraction of day numbers.
2. Decide the rule, counting today or not, and keep it for the whole countdown.
3. Mark days off on a printable yearly calendar, or check the November and December pages for the weeks ahead.
4. Cross-check against a day-of-year milestone. Our story on the 100th day of the year shows how a day number maps to a date.

Printable: days left on the first of each month

The printable on this page is the table above in one sheet: 2026 (common) and 2028 (leap) day numbers and days left for the first of every month. It carries a year in its title because the days-left figures for dates after Feb. 28 are the same in every common year and in every leap year, as the table shows.
