----------------------------------------
Thanks, [~tanclary]
I ended up fixing another issue with the weekday in the same PR. Please, let me
know if any changes are needed.
> Wrong ISOWEEK and no ISOYEAR on BigQuery FORMAT_DATE
> ----------------------------------------------------

> Key: CALCITE-6226
> URL: https://issues.apache.org/jira/browse/CALCITE-6226
> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.34.0, 1.35.0, 1.36.0
> Reporter: Rodrigo Rueda

> Doing:
> {code:java}
> FORMAT_DATE('%G-%V', DATE '2023-01-01'){code}
> results in:
> {code:java}
> '%G-01'{code}
> but should be:
> {code:java}
> 2022-52{code}
>
> The week is wrong because the ISOWEEK format function is not setting the
> minimalDaysInFirstWeek to 4 and the ISOYEAR (%g or %G) was not implemented.
