Like the alignment of planets, there are events that only only occur a few times in a century or millennium. One of such events are the appearance of dates with consecutive numbers, the example of such are the shown below. These dates with only appear once every century if we consider the last two digits of the year, or every millennium if we consider the last three digits.
We are lucky because we are the only generation in this millennium (or century) who are present these consecutive dates. If you are keeping a daily diary, check out what happened on these dates.
When will this phenomenon happen again? In year 3003, 991 years from now if we consider the last three digits of the year. If we consider only the two digits , it will repeat 91 years from now which is in year 2103.
