1,000 days together: when it falls and how to count it

You are nearing 1,000 days together, or sober, and want the date before it passes. The trap is the first day: is it day 0 or day 1? The days-since counter counts it as day 0, so day 1,000 falls exactly 1,000 days after your first day.

A first day of 12 June 2024 reaches day 1,000 on 9 March 2027. Get the rule wrong and you celebrate a day early or a day late. Enter your first day under “The date”, and the counter gives today’s count, the next milestone with its date, and a card to post.

Does the counter count the first day as day 1?

No: the first day is day 0, and the day after it is day 1, because the counter counts whole days elapsed. Given today’s date, it answers “It is today”. Given yesterday’s, it answers “1 day since”.

Some couples count the other way. Daebak, a shop selling Korean goods, writes in its magazine (June 2026) that Korean couples call the day they got together day 1. They reach 100 days “on the 100th day inclusive”. Counted that way, day 1,000 comes one day before the date the counter gives.

When is day 1,000 for my date?

The card names day 1,000 once it is the next milestone, which is from day 900 onward. Before that, it names an earlier step, such as day 900. Here is what the counter showed on 18 September 2026 for three first days:

To see day 1,000 before the card names it, press “Add to my calendar” under the answer. The file lists your next twelve milestones as all-day entries, such as “1,000 days — Together”, and day 1,000 is among them until you reach it.

Which milestones does the counter show?

It follows two ladders and names whichever step comes first. One is round numbers of days: every hundred up to 1,000, then 1,500, 2,000, 2,500 and 3,000, then every thousand up to 10,000, and a few beyond. The other is whole years, on the date of your first day.

Day 1,000 always falls between the second and third anniversaries. For a first day of 23 December 2023, the card for day 1,000 reads “2 years, 8 months and 26 days”. It names the next step: “3 years on Wednesday, December 23, 2026”.

What does the 1,000-day card show?

The card shows the count in large figures, your headline from “What it stands for”, and “since” followed by your first day. On day 1,000 itself it adds a “Day 1,000!” badge. On every day it names the next milestone with its date.

Below come the span in years, months and days, “counted on” with the day’s date, and the weeks so far. The site’s address and a QR code sit in the corner, and the code opens the empty form, never your date.

“Frame” offers Landscape, 1200 × 630, the link preview, or Portrait, 1080 × 1350, the feed and the story. Under the card, “Ready to paste” holds a caption in one sentence: “1,000 days together, 3 years on December 23, 2026.”

Questions

What is 1,000 days in years and months?

Two years, eight months and 24 to 28 days, depending on the months crossed. For a first day of 23 December 2023, the counter wrote “2 years, 8 months and 26 days”.

Which time zone does the count use?

Yours: the page reads today’s date from your device before counting. A count made at 8 p.m. in Denver is not already tomorrow’s, although it is past midnight in Paris.

Can I count down to day 1,000?

Yes: take the date of day 1,000 from the counter and enter it in the countdown card maker. It draws the days left as a card that says the day it was counted on.

Does the counter keep my date?

No: the count is made and the card drawn in the same response. The page offers no link carrying your date, and the calendar file is sent by a form, so the date is never written into an address.
