[Quantlib-users] Why is 2020-12-28 a Target Calendar business day?

[jian Xu <jia...@gm...>]

Hi,
My understanding is that the Target Calendar should have both Dec-25,
and Dec-26 as holiday.  And since 2020-12-26 a Saturday, then
2020-12-28 Monday should be a holiday.  Is this correct?

But when I tried quantlib, I got 2020-12-28 as a business day.  Am I
missing something?  Thanks.

>>> target_cal = ql.TARGET()
>>> target_cal.isBusinessDay(ql.Date(28, 12, 2020))
True

Regards,
Jian
