Days Until Date

Enter any target date to see how many days remain — or how many days ago it was.

Days until

Pick a target date to see how many days remain.

To find the days until a date, subtract the starting date from your target. From 1 January to 25 December 2026 is 358 days — about 51 weeks or 11.8 months. If the target has already passed, the same subtraction turns negative, which this tool reports as days ago.

Counting down to any date

This is a general-purpose countdown: point it at a birthday, a holiday, a wedding, a visa deadline, or a launch date, and it tells you exactly how many days stand between today and that date. The headline number is the days remaining, with weeks and approximate months underneath so you can size the wait at a glance.

Dates in the past are handled too. Pick a date that has already gone by and the count flips to days ago — useful for anniversaries or working out how long since something happened. You can also change the “counting from” date to measure the gap between any two dates rather than from today.

days = target date − start date

A positive result is days until; a negative result is days ago. Both dates are compared at UTC midnight so a daylight-saving change never adds or drops a day.

  1. 1
    Choose the target date. For example, a holiday on 25 December 2026.
  2. 2
    Set the start date. It defaults to today, but you can pick any other day to count from — say 1 January 2026.
  3. 3
    Subtract the start from the target. From 1 January to 25 December 2026 is 358 days (an exclusive count of the gaps between the two dates).
  4. 4
    Read the sub-units. 358 ÷ 7 ≈ 51.1 weeks, and 358 ÷ 30.44 ≈ 11.8 months. The tool shows these automatically.

Days, weeks, and months at a glance

Months and years vary in length, so those columns use average values (≈ 30.44 days per month, 365.25 per year).

Inclusive vs exclusive counting

This tool counts exclusively: it measures the gaps between the two dates, so today to tomorrow is 1 day, not 2. That matches how most countdowns work — “3 days until the exam” means three sleeps away. If you need both endpoints counted (an inclusive count, such as “how many days am I on holiday” when you count both the arrival and departure day), add 1 to the result.

Weekends and holidays are included. The figure is calendar days, so it counts every Saturday, Sunday, and public holiday in the span. If you only care about working days between now and a deadline, use the business days calculator instead, which skips weekends for you.

Does the count include today?
No — it counts exclusively, measuring the gap between the two dates. So if your target is tomorrow, it shows 1 day. Add 1 if you want today counted as part of the total.
What happens if the date is in the past?
The count flips to “days ago”. The subtraction gives a negative number, and the tool shows its size along with a past-date label, so you can measure how long since a date as easily as how long until one.
What does it show when the target is today?
It shows “Today” instead of a number, because zero days separate the target from the start date. The weeks and months sub-stats are hidden since they would both be zero.
How are the weeks and months worked out?
Weeks are the exact day count ÷ 7. Months are approximate: they use the average calendar month of ≈ 30.44 days, because real months range from 28 to 31 days. Treat the months figure as a rough guide, not an exact count.
How is this different from the exam countdown?
This is a general countdown to any date — a birthday, holiday, or deadline — and reports days, weeks, and months. The exam countdown is purpose-built for study, ticking down to the end of your exam day in hours and minutes.
Are weekends and public holidays counted?
Yes. The result is calendar days, so every weekend and holiday in the span is included. For working days only — skipping Saturdays and Sundays — use the business days calculator.
