Yeah, normally, Islamic months are determined by the sighting of the crescent moon (hilal), so technically, the decision should be made after Maghrib when people actually attempt to see the moon.

However, many countries now use astronomical calculations to predict the moon’s visibility in advance. Since astronomers can accurately calculate when the hilal will be visible (or not), some places announce Eid a day early based on these calculations rather than waiting for actual sighting reports.

That said, traditionalists (like Saudi Arabia and some scholars) still insist on physical moon sighting. But in cases where it's almost certain that the moon will be visible based on astronomical data, they announce it early to avoid last-minute confusion.
