About the Days Until Calculator
The Days Until Calculator counts down to any date: a birthday, a wedding, a vacation, a product launch, an exam or a holiday. A live timer shows the days, hours, minutes and seconds that are left, and the list below adds the time in weeks and days, the number of weekdays and how many weekends are still to come.
Give the countdown a name and an optional time, then save it on your device or copy a link to share it. Quick picks fill in New Year, Valentine's Day, Halloween, Christmas and the first day of summer. Dates in the past work too: the timer then counts the time since the event.
The countdown runs on your device's clock and time zone, so it handles daylight saving changes correctly where you are. Saved countdowns stay in your browser; nothing is sent to a server.

Examples
Quick picks on one afternoon
On Saturday, October 10, 2026 at 2:30 PM in New York, the quick picks show:
| Event | Date | Countdown | Weekdays |
|---|---|---|---|
| Halloween | Sat, Oct 31, 2026 | 20 d 9 h 30 min | 15 |
| Christmas | Fri, Dec 25, 2026 | 75 d 10 h 30 min | 54 |
| New Year | Fri, Jan 1, 2027 | 82 d 10 h 30 min | 59 |
| Valentine's Day | Sun, Feb 14, 2027 | 126 d 10 h 30 min | 90 |
| First day of summer | Mon, Jun 21, 2027 | 253 d 9 h 30 min | 180 |
Why 9 h 30 min for some and 10 h 30 min for others? In New York, clocks fall back one hour on November 1, 2026, and spring forward again on March 14, 2027. Countdowns that cross only the fall change get an extra hour. Halloween is before the change, and the first day of summer crosses both changes, so they show the plain 9 h 30 min to midnight.
The subtitle also shows calendar days, which ignore the time of day: New Year is in 83 calendar days, even though fewer than 83 full days are left.
A countdown with a time
Event "Launch", date Monday, November 2, 2026, time 9:00 AM, viewed at the same moment: 22 days, 19 hours, 30 minutes, shown as "Monday, November 2, 2026 at 9:00 AM · in 23 calendar days", with 3 weeks, 2 days, 15 weekdays and 4 weekends.
Weekdays are counted from today, including today, up to the day before the event. Weekends count full Saturday and Sunday pairs.
One link, three time zones
Copy link for New Year at 12:00 AM creates:
…/tools/days-until-calculator?date=2027-01-01&event=New+Year&time=00%3A00Opened at the same moment (October 10, 2026 at 18:30 UTC), the link shows a different countdown in each place, because each viewer counts down to midnight in their own time zone:
| Viewer in | Local time | Countdown |
|---|---|---|
| New York | 2:30 PM | 82 d 10 h 30 min |
| Los Angeles | 11:30 AM | 82 d 13 h 30 min |
| London | 7:30 PM | 82 d 5 h 30 min |
That is right for New Year's Eve, which everyone celebrates at their own midnight. For a single global moment, such as a live stream, tell everyone the time zone, or use the Timestamp Converter to show that moment in each zone.
A date in the past
Pick July 4, 2026 on the same day and the title changes to "Since …", with "98 calendar days ago" under the timer.
Tips
- Add a time for anything that does not start at midnight, like a flight or a concert. Without one, the countdown ends at the very start of the day.
- Save countdowns you check often. They stay in your browser, and the list shows how many days are left at a glance.
- Share a link instead of a screenshot. The link keeps counting, and each person sees it in their own time zone.
- Planning work before a deadline? Use the weekday count, then subtract holidays and days off.
- For the days between two dates that are not today, the Date Difference Calculator gives the same breakdown with more options.
Common mistakes and limits
- Sharing a link for a single global momentThe link has no time zone, so every viewer counts down to that clock time where they are. State the time zone in your message.
- Expecting saved countdowns on another deviceThey are stored in this browser only. Use Copy link to open a countdown elsewhere.
- Reading calendar days as full days"In 83 calendar days" counts dates, not 24-hour periods. The timer shows the exact time left.
- Expecting summer to start on June 21 every yearThe quick pick uses the date of the June solstice where you are. It moves between June 20 and 21: in 2028 it is June 20 in New York but June 21 in Tokyo. Weather services count summer from June 1, and in the Southern Hemisphere the June solstice starts winter.
- Counting weekdays as working daysWeekdays are Monday to Friday, including public holidays. Subtract the holidays that apply to you.
