Date and source policy
- Included here
- 1 upcoming science countdown; past entries are kept off this indexed hub.

Source policy reviewed Apr 30, 2026. Category hubs aggregate source-linked records from the countdown catalog. Feed-derived entries keep their certainty labels, and the detail page remains the final place to verify the source.
Confirmation checklist
How to use science countdowns
Choose by certainty
Cards label expected and windowed records so users can separate firm dates from monitoring targets.
Open the detail page
Detail pages carry the source URL, schema posture, local-time handling, and reminder controls.
Check adjacent views
Use year and region paths when the next useful event is outside this category list.
Act only after source review
The hub is a discovery surface; logistics still belong to the linked source on each event page.
Category explainer
Browsing science countdowns
This page is a filtered listing — every card below is one science event with its own countdown. Category browsing is the right axis when the next relevant date matters more than any one specific event.
What defines this category
Science groups events by subject type. Scientific announcements, prize ceremonies, and scheduled disclosures.
Why browse by category
Category browsing answers "what science event is next" without needing a specific title — distinct from year browsing (everything in one calendar year) or region browsing (one jurisdiction across all topics).
What is in view now
1 upcoming science countdown across 2028.
How the list is filtered
Past-dated events drop off this indexed hub automatically. The catalog revalidates hourly, so a date moving into the past removes its card on the next rebuild window.
Category, region, and year listings are three different cuts of the same tracked-event catalog. Use the related links below to switch axes when the next useful date is outside this category.
