Team,

Extracting the week from a date gives wrong results for the last two days of 2024.

SELECT EXTRACT (WEEK FROM DATE '20241230');

or

SELECT EXTRACT (WEEK FROM DATE '20241231');

both result in a value of  1
which is wrong, obviously...

The expected result is 53

The results for the year 2020 are correct:
SELECT EXTRACT (WEEK FROM DATE '20201230');
results to 53
