How Many Days Are Left in the Year?

The count for today

To count from or to any other date, such as a deadline or a birthday, use the Days Between Dates Calculator.

What each number counts

Pages that say "77 days left" rarely say whether today is in that number. Here is a worked example with a fixed date, Thursday, October 15, 2026, which is day 288 of 365. The count for your own today is in the section above.

The three always add up to the days in the year: 287 + 1 + 77 = 365. If you count today as one of the days left, there are 78. Today's day number is the days passed plus one, so day 288 means 287 days came before it.

Work it out yourself

1. Add up the days in the months before this one. For October 2026: 31 + 28 + 31 + 30 + 31 + 30 + 31 + 31 + 30 = 273.
2. Add today's date to get the day number: 273 + 15 = 288.
3. Days passed before today are the day number minus 1: 288 − 1 = 287.
4. Days left after today are the days in the year minus the day number: 365 − 288 = 77.

The same numbers in Excel or Google Sheets, for today's date:

Format both cells as numbers, not dates, or the spreadsheet shows a date instead.

Day of the year calendar

Each date shows its day number underneath. Today is highlighted. Useful for logs, shipping and lab dates, and anything that counts days from January 1.

Days passed and left at the start of each month

The current month is highlighted. In a leap year every date from March 1 has a day number one higher, because of February 29, so the table always uses this year's real calendar.

Days since January 1 of earlier years

Counted up to today, not including today. Each full year adds 365 days, or 366 when it holds a February 29.
