Today is the 736,000th day since Jan 1, 0001!
I went to timeanddate.com to double-check the math. On their homepage, they have a promo to print our 2016 calendar (archived screenshot). At first glance when I saw the image, I thought, “WOW! HOW DO THEY HAVE A PHOTO OF MY CALENDAR!” and then I realized, earlier this year I printed out their calendar and have it hanging up in my cube.
It is indeed 736,000 days since the start of AD. What would this special day be called?
- The Thousand day?
- Thousandth Day?
- Happy 737 Thousandth Day?
- or happy 737th Thousand Day

Branden M came up with the name KiloDay via an instant message chat. The name is very fitting for the 1,000th day. We’ll have to wait another 2 years, 8 months, 27 days until the next KiloDay on November 1, 2018.
It would be cool if something like the Olympics happened every 1,000 days. Just to make us aware of how long 1,000 days is. What should be the celebration tradition for the KiloDay?
Here are the upcoming Kilodays:
- 737,000th day: Thursday, November 1, 2018
- 738,000th day: Wednesday, July 28, 2021
- 739,000th day: Tuesday, April 23, 2024
- 740,000th day: Monday, January 19, 2027
- 750,000th day: Friday June 5, 2054
- 777,777th day: Saturday, June 24, 2130
And some of the past Kilodays:
- 500,000th day: Wednesday December 5, 1369
- 666,666th day: April 8, 1826
- 733,000th day: Monday, November 19, 2007
- 734,000th day: Sunday, August 15, 2010
- 735,000th day: Saturday, May 11, 2013
- 736,000th day: Friday, February 5, 2016
Etym: February 5, 2016 is exactly the 736,000th day since January 1, 0001.
Worm: That makes today the 736th KiloDay.
Note: Mark your calendars. The next KiloDay (737,000) will be on November 1, 2018
I’d like to see a chart with all the milestone KiloDays. (1,000, 10,000, 100,000, 200,000, 250,000, etc.) and show what calendars dates they are and what events in history happened on those days.
I was able to know that today was the 736,000th day, because in a blog post from 2007, I made a google calendar. https://www.spudart.org/blog/today-is-day-732951/
I came across that old blog post by googling for “736,000th day“. Oddly, my blog post was the only result. Nobody else has ever written about the 736,000th day.

Now there are some results for: “736,000 days” but they are more in reference to mathematical formulas to calculate days–not for the celebration of the milestone of 736,000 days. Sometimes the Internet does seem small.
I totally missed day 737,000.
