Release calendar

US economic data release calendar

When does the next CPI come out? When does the debt number move? The official release rhythm of the data this platform serves — and the moment the API picks each release up.

CPI · monthly

CPI releases — remaining 2026 dates

The Bureau of Labor Statistics pre-announces every CPI release for the year. All releases at 8:30 AM ET. The reference month is always the month before the release date.

Dates per the official BLS CPI release schedule. The BLS occasionally reschedules — the official page is always authoritative.

The December 2026 CPI is released in January 2027, on the 2027 schedule.

National debt · daily

National debt — every business day

The Treasury publishes each business day's Debt to the Penny figure one business day later, around 3:00 PM ET.

The publication pattern

T+1 · ~3 PM ET
  • Daily, weekends and federal holidays excluded — no annual calendar to track.
  • The source never froze during federal shutdowns (verified through Oct–Nov 2025).

Interest rates & annual series

Monthly & annual
  • Average interest rates: monthly, published with the Treasury's month-end data.
  • Historical Debt Outstanding (1790+): one new record per fiscal year end (September 30).

Your integration

What this means for your integration

Ingestion is automatic on every release. Your code never has to know the calendar — but if you poll, these dates are when polling pays.

From the official release to your response

1The agency publishes: CPI at 8:30 AM ET, the debt one business day later, around 3:00 PM ET.
2Ingestion runs on its own: CPI and famous prices refresh on release day, the debt every business day after publication.
3The new month simply appears in /inflation/latest. Poll cheaply — every response ships ETag, so If-None-Match turns unchanged data into a 304.

Missing months stay missing. If the government doesn't publish (e.g. October 2025, federal shutdown), the API serves the hole as null — never an estimate.
