Tokyo
This next part is a little confusing. According to the Rov I asked, Tokyo is Halachically one day behind what they say it is. Therefore, when we left Beijing Tuesday afternoon, we arrived in Tokyo Monday night (Halachically). This worked out very well for us as we were in Tokyo on (their) Thursday which was a Ta'anis and we were also in Honolulu on (the real) Thursday. (This was because we took a 10pm flight (their) Thursday night and arrived in Honolulu on Thursday morning.) The Rov I asked informed me that I needed to fast only once starting from when it got light on the plane on the way to Honolulu. Please, ask your own Rov when it comes to travelling to Tokyo and Honolulu.
Hi Eli,
Thank you for the detailed trip report. My husband and I are thinking of doing JFK-LAX-TYO-HON-LAX using our miles. We haven't booked the trip yet, and I wanted to clarify with you what you meant about Tokyo being one day behind. We were planning on arriving to Tokyo on a Monday and leaving to Honolulu on a Sunday. If we leave on Sunday, are we technically flying out on Shabbos?
