The Mars Sol Date block lets you display the post’s published date in terms of Martian sols, starting from Sol 1 at the first post on your site. 
A Martian sol is approximately 24 hours, 39 minutes, and 35 seconds long. 
Perfect for science blogs and Mars enthusiasts, the block automatically calculates and displays something like “Sol 51”.
How it works: 
– Sol 1 is the timestamp of your site’s first published post. 
– Each Martian sol is 24h 39m 35s (88775 Earth seconds). 
– For each post, the block computes the sol number based on the time difference between that post and the site’s first post.
No configuration required — just insert the block wherever you wish to show the sol date!

Automattic

The Crowdsignal Forms plugin allows you to create and manage polls right from within the block editor. 
Creating polls is as simple and as fast as writing a bullet point list. No embed blocks and no copy pasting needed anymore.
Customize the look and feel of your polls to match your brand, and pick your favorite color. The poll block supports the styling of your theme by default, and from there you can customize the styling of your polls the way you want.
With Crowdsignal’s results page you can view all responses as they come in. See the geo-locations of your voters and analyze IP addresses for any suspicious voting behavior. See advanced stats and analytics for understanding your audience.
Analyze your results and then export them in a number of different formats.
Set close dates for polls, create polls with single or multiple choice answers, choose whether to show your readers the poll results or keep them private.
You can create an unlimited number of polls with a free <a href="https://crowdsignal.com/" rel="nofollow ugc">Crowdsignal</a> account and your first 2,500 signals are free. A signal is a response you get to a poll. If you are on a free plan, you still have full access to the first 2,500 signals. Any further responses you collect will still be recorded but if you <a href="https://crowdsignal.com/pricing/" rel="nofollow ugc">upgrade</a> you will get access to our unlocked reports to see them. You’ll also get access to a <a href="https://crowdsignal.com/features/" rel="nofollow ugc">range of features</a> not available to free users.

I'm still amazed on how much more traction a post can have by adding visitor interaction to it. Allowing your readers to have an opinion, learning from their answers and make better decisions relying on actual data. Priceless.
