This international date line near Fiji is consensus of the modern world, that it is Thursday behind this line and Friday after the line. Or it is 30th April behind the line and it is 1st of May after the line.
My question is what is the importance of this line in Islamic Shariah.
Or where Islamic Thursday ends and Friday starts. Does it happen at Makkah. Or we follow the current consensus of the modern world.
For Islamic date we have Hilal visibility curve.
A good homework for people who say, we have landed on moon and we don't use science for moon sighting.
