11/12/13 - is this one of the most iconic dates of the year? Not really. But certainly one can appreciate the rarity of it.
Today is the last time this century the date lines up in consecutive order.
Think about it: the 11th day of the 12th month of the 13th year in the millennium.
Charles Sturt University mathematics lecturer Kenneth Russell said calendrical sequence only happens 11 times a century.
"It happens 11 years in a row and then it doesn't happen again for a long time," he said.
"So you will have to wait until 1 February 2103 for the dates to line up again.
"It's a fairly rare sequence."
Even though Wagga Christian College students Dikeni Tuombemola, Liam Spicer and Kyle Hughes are not mathematicians, the unusual date bears a special kind of significance for them.
They are all celebrating their birthday today.
Turning 13, Kyle Hughes is looking forward to relinquishing his share of the household chores for his birthday.
"I asked my mum for the whole series of The Walking Dead so hopefully I get to watch it," he said.
Kyle said the date was a "coincidence" but didn't care too much for what it means.
"It seems every year there is something that doesn't happen for a hundred years," he said.
"It's weird but these things happen all the time."
Dikeni Tuombemola said the date was "cool" but said she was more focused on her teenage years.
"I'm looking forward to finding a part-time job," she said.
Kyle and Dikeni will be 103 by the time their calendars are next graced with numerical purity.
