IN England there was some differences- some accepted the KSA view and did Eid on Tuesday, whereas some went with it being Wednesday 1st Oct.
Generally I have been following my local mosque and they followed Saudi and other parts of the muslim world that also did it on Tuesday.
However, I am becoming more convinced with moonsighting done by astronomical calculations- but only stop at the fact that the sunnah was and is that when a muslim whose character is sound and has healthy eyesight sees the crescent, then ramadan/eid can be observed.
Allah knows best.
And Eid Mubarak to all my bros and sisters around the world.
