Days until your product launch

Pick the launch date and the countdown shows the days remaining from today, broken into weeks and days, plus the weekday.

Enter the launch date to see exactly how many days are left to ship.

Pick a valid date to start the countdown.

The countdown is measured from your device's local date today to the date you choose, in whole days.

How does it work?

Days are counted in whole calendar days using UTC, so the result is unaffected by time zones or daylight saving. A negative count means the date has already passed.

Days-until formula

d=target−todayd = \text{target} - \text{today}
d
Whole days between today and the target date.
target
The date you are counting down to.
today
The current date (your local today).

From 1 June to 1 July is 30 days.

Method & sources

We count whole calendar days from today to the date you choose. Both dates are handled in UTC so time zones and daylight saving never shift the result. You pick the target date yourself — the calculator does not look up holidays or official calendars.

How we calculate

  • The count is whole days from today to the date you choose.
  • Today is your device's local date; the target date is the one you pick.
  • A negative count means the date has already passed.
  • The day of the week shown is the weekday the target date falls on.

Rounding

The countdown is in whole calendar days. Today and the target date are counted in UTC, so time zones and daylight saving never shift the result.

What this countdown does

A launch date is the one date a whole team works backwards from, and it is also the one everybody remembers differently. This countdown makes it a single number: days remaining, the same figure in weeks and days, and the weekday it lands on. Because it always counts from today, a shared link stays correct for everyone rather than going stale the way a number typed into a slide does.

How to use it

  1. Pick the date you're counting down to.
  2. Read the days remaining at the top.
  3. Check the weeks-and-days breakdown and the weekday it falls on.
  4. Use Share to send the live countdown to anyone.

When it's useful

The weeks-and-days view is the useful one for planning. Work gets scheduled in sprints and weeks, not in raw day counts, so "seven weeks and two days" maps onto a plan in a way that "51 days" does not. It is also the fastest way to settle whether a piece of scope still fits.

The weekday matters more than the date

Check the weekday before you commit to a launch date. Shipping on a Friday means any problem lands on a weekend, with a thinner team and slower response times. The day before a public holiday has the same problem in a longer form. Mid-week — Tuesday to Thursday — gives you working days on both sides of the release, which is usually worth more than the marginal benefit of any particular date.

Run two countdowns, not one

The date that actually governs the work is rarely launch day itself. Code freeze, the security review, the last date translations can be handed off, or the deadline for press materials all come earlier, and they are the ones that slip first. Set a second countdown to whichever of those is your real constraint, and use the launch-day one for the announcement. If the gap between them is smaller than you expected, that is the useful finding.

A rough backwards plan

  • 8 weeks out: lock the scope. Anything added after this point comes out of quality or out of the date.
  • 6 weeks out: copy, screenshots, pricing pages, and translations — the assets that always take longer than the estimate.
  • 4 weeks out: beta or limited release, whatever you can get real usage from while there is still time to react.
  • 2 weeks out: code freeze, support documentation, and a briefed support team.
  • 1 week out: a full dry run of the release, including the rollback path.
  • Launch day: ship in the morning, so the people who built it are still available in the afternoon.
  • 1 week after: the review, while everyone still remembers what actually happened.

Treat the milestones as a starting shape rather than a rule — a small release compresses the whole thing, and a regulated one stretches it.

How the days are counted

The count is in whole calendar days from today to the date you pick, calculated in UTC so it never drifts with time zones or daylight saving. If the date has already passed, the count shows how many days ago it was.

FAQ

How many days until launch?
Pick the launch date above and the countdown shows the exact number of days remaining from today.
What does the weekday tell me?
Which day of the week launch day falls on. It is worth checking before the date is fixed: a Friday release puts any problem into the weekend, while mid-week leaves working days on both sides.
Does it count working days or calendar days?
Calendar days. If you need the number of working days between two dates, that is a different calculation — this countdown deliberately counts every day, including weekends and holidays.
Can I use it for the code freeze instead?
Yes, and it is often the more useful date. Enter whichever milestone actually constrains the work, and run a second countdown for launch day itself.
Can I share the countdown with the team?
Yes. The share link reopens the countdown on the same date and recalculates from each reader's own today, so it does not go stale the way a hardcoded number does.
What if the launch date moves?
Enter the new date and the countdown updates immediately. Nothing is stored, so there is no old date left behind to confuse anyone.
Can I share the countdown?
Yes. Share copies a link that reopens the countdown to the same date, always counting from the viewer's today.
