How to use the days left in the year calculator
Check the date
The date box starts on today. Leave it as it is to see how many days are left in the year right now.
Pick another date if you need to
Choose any date to see the days left from then. This helps when you plan a project or a budget that starts later.
Decide about the selected day
Choose No to count only the days after the selected date. Choose Yes to count the selected day too.
Read the result
The big number is the days left. Below it you get weeks, weekdays, weekend days, months left and the percent of the year completed.
How days left in the year are calculated
Every date has a day number inside its year. January 1 is day 1 and December 31 is day 365, or day 366 in a leap year. The days left are the total days in the year minus the day number of your date.
Days left in the year
Days left = days in the year − day of the year
Days in the year = 365, or 366 in a leap year
Percent done = day of the year ÷ days in the year × 100
A year is a leap year when it divides by 4, except century years that do not divide by 400. So 2028 is a leap year, but 2100 is not.
Days left in the year examples
Example 1: Early in the year
Start from January 1, 2027, which is day 1 of 365.
- Days in 2027 365
- Day of the year 1
- Days left 364
- Weeks and days left 52 weeks
- Weekdays left 260
The first day of the year leaves 364 days, which is exactly 52 weeks.
Example 2: Around the middle of the year
Start from July 4, 2026, which is day 185 of 365.
- Days in 2026 365
- Day of the year 185
- Days left 180
- Weeks and days left 25 weeks, 5 days
- Percent of year done 50.7%
July 4 sits just past the halfway point, so a little over half of the year is already behind you.
Example 3: A leap year
Start from March 1, 2028. Because February 2028 has 29 days, this is day 61 of 366.
- Days in 2028 366
- Day of the year 61
- Days left 305
- Weekdays left 217
- Weekend days left 88
The extra leap day adds one more day to the year, so the same calendar date leaves one more day than in a normal year.
Where a days left in the year calculator helps
Goals and planning
See how much time is left to finish yearly goals, projects or a fitness plan.
Budgets and sales targets
Spread a yearly target over the days or weeks that remain.
Work and deadlines
Count the weekdays left before year end to plan work and time off.
Tax and benefit dates
Check how long you have to use leave, benefits or year end deadlines.
The days left and the days passed always add up to the days in the year. On a normal year they add up to 365. Choosing Yes under the count option adds the selected day to the days left, so the two numbers then overlap by one day.
