In the UK if you started fasting on 30 June, Eid al Fitr should be on Wednesday, 30 July. If you started on the 29 June, Eid will be on Tuesday, 29 July. People in the Americas might be celebrating Eid as early as Monday, if they started fasting on the 27 June.
As for reports of the moon’s sighting before then, no need to over react! 🙂
