330: Date type metric must be reported with format 'yyyy-mm-dd'
Recorded as a finding also shown as EBA.330
Official text
Date type metric must be reported with format 'yyyy-mm-dd'
How it appears in feedback
[table],[row],[column],330, Date type metric must be reported with format 'yyyy-mm-dd'
What triggers it
A date is not yyyy-mm-dd: 31-12-2025, 2025-31-12, 2025/12/31 or '2025-01-31 00:00:00' all fail. Excel silently reformats dates on save, which is the usual cause.
A date is not in yyyy-mm-dd form. Excel often rewrites dates as dd/mm/yyyy or as a serial number like 45658.
Templates: B_02.02 (c0070 start, c0080 end, c0090 termination, c0100 notice), B_06.01 c0070, B_07.01, B_01.02 c0100
How to fix it
Edit CSVs in a text editor, never save from Excel; end date for open-ended contracts is 9999-12-31 (AFM Q&A).
Format date columns as text before export, or fix them after export. 2026-12-31, nothing else.
