Each day I tweet about the number associated with my diurnal age but I rarely look back at any of these tweets, especially now that they just represent a summary of a far more detailed analysis that I have stored on my AirTable databases (Diurnal Age Part 1 and Diurnal Age Part 2).
However, this was not always the case and intially my daily tweet was the only record I retained of my analysis. I discovered a site (https://www.allmytweets.net/) that allows you to easily look back at all your previous tweets and it was interesting to look back at my very first tweet on April 30th 2015. See Figure 1.

Short and sweet but this was back in the days where only 140 characters were allowed. It was only on November 8th 2017 that Twitter increased the limit to 280 characters. This is the OEIS sequence to which the tweet refers:
A109724 | Sum of the first \(n^2\) primes. |
The initial members of the sequence are:
0, 2, 17, 100, 381, 1060, 2427, 4888, 8893, 15116, 24133, 36888, 54169, 77136, 106733, 144526, 191755, 249748, 320705, 406048, 507825, 627294, 768373, 931686, 1119887, 1336090, 1583293, 1864190, 2180741, 2536646, 2935471, 3380980
In the case of 24133, \(n\) has the value 10. I didn't tweet the next day but did for 24135 and then I missed another day and tweeted for 24137. After that I kept tweeting for every day without fail until the day of this post. The tweets were not exclusively mathematical in those days. It was only on August 6th 2016 (24588) that the tweets became solely mathematical.
I'll still keep tweeting, old habits die hard, even though my AirTable database and my mathematical blog (Mathematical Meanderings) are the foci of my mathematical analysis these days.
Of course I was counting days long before I started tweeting about them. Here is a graphic I created to celebrate being 22222 days old. This occurred on Thursday, February 4th 2010!
