Reporting a calculation issue

Include the calculation mode, selected calendar, endpoint rules, snapshot version and expected result. If a holiday is missing or incorrect, include a link to the official source. Use a non-sensitive example where possible.

Other enquiries

The same address accepts accessibility feedback, source corrections and privacy requests. This is a direct email contact, not a live support service; we do not promise a response time.

Before reporting a difference, check the holiday scope and counting rules. A bank, employer or trading calendar may intentionally differ from the federal and regional calendars provided here.
