I saw "import from LinkedIn" and closed the tab.

Yeah no I don't want to use lifetime trackers on myself. It is a trigger for depression

Very cool! Thanks for including psychophysics setting. I wish there was one for date format because mm/dd/yyyy breaks my brain a little.

I like the use of the Weber-Fechner law, that's a lens I use to think of age as well :) The idea is that experienced time is proportional to log time, i.e. it's why time seems to move faster as we age. You could even measure your age in powers of two, like we do octaves.

Are you saying that a better way to measure perceived time is something like "1 year, 2 more years, 4 more years, 8 more years," starting from birth, and maybe call each of those increments a "log year"? I like it.

I guess the "natural" base to use to get the "right" number of increments is a pointless exercise, since it ultimately bottoms out in the question of "why is a regular year as long as it is?", but if we assume a base of 2, I'm currently in my 6th log year, and hope to die comfortably into my 7th. Actuarial odds are >80% in my favor.

Yes! But I do agree, six or seven units are not enough.

Extending the music analogy, we could call those powers of two "octaves", and divide it into twelve exponentially-spaced steps (i.e. 2^(years/12)).

The break even is about 75 steps (i.e. six octaves and three steps), which is about 76 years, since 2^(75/12) = 76.1.

Hi, I made this! I don't know how it got to this page. Thanks for the support :)

Thanks for making this. Genuinely something I needed, but not enough to actually build it. ^^

(Hope this doesn't sound wrong. I believe the "trimming hangnails" is an important and often overlooked job.)

Love it!

Bug report, if you're the author: I can't delete periods.

Feature request: I wanna be able to move periods from one layer to another.

What platform / browser? Note that if you opened through a shared link you may be in view only mode. If that's the case I'll try making it more obvious

nevermind, got a repro. thanks

Bug is fixed, request backlogged :)

So what is it for? To know how life periods span and change one into another? I like it but I am struggling to find a use case

Design is amazing. Well done. I inserted my birthday and got "Enter a real Gregorian date.". Only then I understood I needed to insert "mm dd yyyy". User error for sure :) but this date format really annoys me

It should be browser locale/region dependent. You may be able to fix it globally from your browser settings.

Hmm, I'm using Safari and don't see anything like this in the browser settings. And the OS is definitely set up to use the one true way.

Like I said "user error" :). you're right thanks!

As a 54 year old, viewing the grid with the Weber-Fechner "psychophysics" grid is depressing as hell. Thanks.
