How does a man divide his time between his two wives during Eid?

Whoever has two wives must be just between them in the division of time, allocating to each wife a day and a night (with the night being more emphasized). The day of Eid should be for the wife whose turn it is. It is not permissible for him to enter upon one of them during the turn of the other except with the permission of the one whose turn it is or for a necessity. If the wife whose turn it is on Eid day agrees to divide her time with her co-wife, then there is no harm.
