October 3 is a day on the calendar. It comes after October 2 and before October 4. It is a special day for some people because important things have happened on that day in the past. It is like a birthday or a holiday, but not everyone celebrates it the same way. Some people might remember it as a day they met someone special or a day they accomplished a big goal. Others might not think it is important at all. But for many people, October 3 is just another day to go about their regular routines.
