ZD: you are correct as to where the dateline is. The Chazon Ish’s dateline runs through several contiguous land masses (Russia, Asia, Australia). According to the Chazon Ish you can’t have one land mass having two separate days (i.e. Australia West of the dateline is shabbos and east of the dateline is Friday). Therefore his dateline is not straight but curves along the east coast of the various land masses (i.e. the entire Australia is considered West of the dateline as is Yerushalim). As Iacisrmma stated above, R’ Tukatzinsky’s dateline divides Alaska. We do not know what his shita is regarding a contiguous land mass. Do we treat the entire Alaska as being West of the dateline or east of it? If it is west then Shabbos would be on what we call Friday; if east of the dateline it would be Shabbos on what we call Saturday; either way it is a safeik within his shita. Hawaii is definitely west of his dateline therefore according to R’ Takutszinsky it is vadai Shabbos on what we call Friday.
