Days Until is a personal tracker for named time intervals.
You define a start date and an end date, give the interval a name — "Summer holiday", "House renovation", "Q3 sprint" — and the app shows how many days have elapsed, how many remain, and a visual progress bar.
Intervals are private to your account by default. You can optionally share a collection of intervals publicly using a share group, which gets its own human-readable link.

Register with your email address and a password. If the instance has email configured, you will receive a verification link — click it before signing in for the first time.
The login page. Use email + password, or a passwordless magic link if configured.
Click the + Add button in the top right. Fill in the name, start date, and end date. You can pick a color using the swatches or the color picker.

Each interval card shows:
Click the edit icon on any card to open the edit form. Change the name, dates, color, or share group assignment. To remove it entirely, use the delete button inside the form.
Share groups let you publish a collection of intervals at a public URL. Anyone with the link can see the intervals in that group — no account required.
Click the Groups button in the header. Enter a name for your group
(for example, "Trips") and click Create.
The group gets a unique link like /g/forest-harbor-otter.
Edit any interval and choose the group from the Share group dropdown. The interval will appear on the group's public page immediately.
Copy the link shown under the group name and send it to anyone you want to share with. The public page shows only the intervals you assigned to that group.
A public share group page — visible to anyone with the link, no login needed.
Three methods are available depending on how the instance is configured:
Click your username button in the header to open the Account panel. From there you can update your display name, which appears on public share group pages.
You can also delete your account from this panel. Deletion is permanent and removes all your intervals and share groups.
