Dates are always somewhat ambiguous, the exact date depends on whether local time is used (and local time where) or Universal Time—for events on the surface of the Earth, local time is probably best but for an event that spans across the planet, it is not clear which local time to use!. For events in space it is more ambiguous. Further for dates after the original adoption of the Gregorian calendar but before it became accepted in different countries, the date given may be a Julian date or a Gregorian date depending upon where the event occurred. And, even the year may be different since the first of the year has not always been January 1 in all countries! The attempt is to use a date that is the one that is typically given.
