Qurbaani in Saudi Arabia and South Africa

Asalaamualaikum mufi

Shukran for answering my question (15813)
can I just get more clarity on this question please.

say for example Eid in Saudi Arabia is on monday and Eid in South Africa is on tuesday, and if my wife does the qurbaani on tuesday, will my Qurbaani be valid considering the fact that it is done in the 3 days of slaughter?
which is monday,tuesday and wednesday.

I will not be slaughtering on monday in saudi she will do it on tusday in South Africa

is this valid?
