After a chat with @Platinum yesterday about this specific Logseq feature missing in SB.
I had a little spare time today, to make this datepicker slash-command as a SIlverbullet Library
You can find it in Mr-xRed Silverbullet Library Repo
By adding this to your repo sources:
https://github.com/Mr-xRed/silverbullet-libraries/blob/main/Repository/Mr-xRed.md
@Mr.Red have tried “github:deepkn/silverbullet-nldates/nldates.plug.js” it’s amazing to manage dates.
So totally cool @Mr.Red, thank you for sharing this lightning fast!
I’m asking GPT to add keyboard navigation to the dates now!
They both have very different use cases:
Done:
h/j/k/l and arrow keys for changing datest to go back to todayWEEK_START)[[2025-12-28]], or 2025-12-28 or [scheduled: 2025-12-28] etc.Now, one can type - [ ] Buy soap /scheduled, and with only a single keystroke (enter), schedule it for today, or use your favorite keys to visually pick a date, and end up with - [ ] Buy soap [scheduled: 2025-12-28]! So cool.
Thank you so much again @Mr.Red, this is terrific!
here is a quick feedback to your version:
the arrow key navigation will also move the cursor on the page, making the insertion inacurate and in other place where the slashcommand was inserted… (h/j/k/l works well)
this wasn’t an issue in my version.
if you change the week to start on Sundays, only the header is changed and everything else stays the same:
This is a great addition and flexible approach!
if you correct these bugs, and if you want I can add your changes to my library.
Love seeing this collaboration! Very nice.
Much appreciate the feedback @Mr.Red !
Oops on the WEEK_START bug, will fix, probably later today.
The arrow key navigation is not affecting me. Perhaps because it’s doing what you say, but I save and restore the cursor in my latest version? Wouldn’t h/j/k/l also cause the same problem for someone using vim keys in their main editor?
Focus shifting back: hmm, it seemed like a problem for me, perhaps because I was using arrow keys in an earlier version and unwittingly causing focus to go away?
On these two issues, suggestions appreciated, as I know next to nothing about web related things.
vim user here so this is very much appreciated.
Oh wow, this was a nasty bug. WEEK_START did not work only when set to 0. Feel free to critique my code, first time writing Javascript.
// old, did not work:
// const WEEK_START = ]] .. tostring(WEEK_START) .. [[;
// fixed:
// Coerce WEEK_START to a number
const WEEK_START = Number(]] .. tostring(WEEK_START or 0) .. [[) || 0;
Other than this, everything else works at my end @Mr.Red. Feel free to let me know if the arrow keys is still an issue or if not, feel free to merge this code to your repo. Thank you!
Haha i would never do that 
I also doesn’t consider myself a pro in JS or in any language to be honest. I mostly use LLM to code, and do some debuging and styling by hand. i understand code when i read it, but i couldnt write it without LLM’s 
Yep, I wouldn’t have either. But when set to zero, the injected JS has weekday set to NaN as it somehow doesn’t recognize it.
instead f numbers i would use: true/false for example:
WeekStartSun = true
or something like that, imho better approach than 0/1
It’s actually designed to be configurable to any day, and so, it accepts values between 0 and 6 (can’t be a boolean).
The root issue is how the lua->JS injection is done which necessitated the check for 0 alone as a special case. Apparently this is a common pattern. I’ll leave it this way 
BTW, wondering if you’ve considered picking a license for your repo?
