cozimjewish:- Your assertion is on the ball, and so absolutely correct. BTW:- In light of this, I usually end up blessing Birkas haIlanos twice annually, once in Tishri whilst in Australia, & once in Nisson whilst in England or Israel.
I also usually manage to coordinate my schedule, to be in Australia over Shiva Ossur bTamuz, and to be in England over Assoro bTeves.
But the flip-back cozimjewish is having to file taxes in 3 countries, and I require the specialized services of an International accountant, as this is quite complex to say the least.
