[mroeschke]

This was deprecated in 1.1.0 and now it's suggested to use DatetimeIndex.isocalendar().week instead

This was deprecated in 1.1.0 and now it's suggested to use DatetimeIndex.isocalendar().week instead

It should be removed from the docs if that is the case.

[mroeschke]

Could you share where this still exists in the docs?

See the link in the initial comment.

@mroeschke The reference to week and weekofyear attributes still exists in the user gude, link here: Time/date components.

df.col.dt.isocalendar().week ?
