2b:null 2c:["$","title",null,{"children":"Circadian Journey | Thad Kerosky | Observable"}] 31:T615,### "Hello Circadian World Journey" Rationale On a recent podcast, software developer [John Carmack](https://lexfridman.com/john-carmack/) mentioned going to bed an hour later each night and just drifting. I've done this for years. There's a lot of talk about actual jetlag and being able to stay up an hour later a lot more easily than waking an hour earlier. Some people have a lot of inflammation, headaches, exhaustion, and trouble setting the routine when they try to jump sleep back hours. **This tool offers a gradual organic solution when you've tried everything else**: set up your life & calendar for a week or two so you can take your sleep cycle further forward 15-20 timezones so it's back to a desirable position. Timeshift "travel" the world from your bedroom. Sleep and digestion are closely related. I've been aided by the "30g of protein within 30 min of waking" rule (e.g. [½](https://youtu.be/doupx8SAs5Y?t=3613) pack of cottage cheese). Sufficient extreme light exposure such as direct sunlight or [artificial LED lights](https://meaningness.com/sad-light-lumens), and ample vitamin D (not necessarily supplemented just before bed) are also factors in maintaining sleep. A recent version of the DSM diagnostic manual [includes a section on the high rate of sleep issues with ADHD](https://twitter.com/CatieOsaurus/status/1746223939410358473). When you try the tool, if the first day isn't starting at your `recent wakeup time`, exactly, and ending at `Hours to Advance per day`, then try adjusting this fudge factor to make it so:32:T853,events = [...Array(numOfDays)].map((q, i) => { const dt = new Date(mostRecentWakeup); const dtstart = new Date(mostRecentWakeup); dtstart.setMinutes( dtstart.getMinutes() + i * hoursToAdvance * 60 - sleepDuration * 60 ); dtstart.setDate(dtstart.getDate() + i); dt.setMinutes(dt.getMinutes() + i * hoursToAdvance * 60); dt.setDate(dt.getDate() + i); let tzname = ""; let offsetTo12 = 0; let offsetAmPm = "AM"; let offsetAmPm24hr = 0; offsetTo12 = dtstart.toLocaleTimeString().split(":")[0]; offsetAmPm = dtstart.toLocaleTimeString().split(" ")[1] === "PM" ? -1 : 1; offsetAmPm24hr = dtstart.toLocaleTimeString().split(" ")[1] === "PM" ? 12 : 0; const offsetAmPmFor12 = offsetTo12 === "12" && offsetAmPm === 1 ? 0 : offsetTo12 === "12" && offsetAmPm === -1 ? 0 : offsetAmPm; const offsetAmPmFor24 = offsetTo12 === "12" && offsetAmPm === 1 ? -12 : offsetTo12 === "12" && offsetAmPm === -1 ? 0 : offsetAmPm24hr; const lookupTzOffset = Number(offsetTo12) * Number(offsetAmPm); const lookupTzOffsetHr = Number(offsetTo12) * Number(offsetAmPmFor12); const lookupOffset24Hr = Number(offsetTo12) + Number(offsetAmPmFor24); const lookupTzOffset24HrWithTZ = (Number(offsetTo12) + Number(offsetAmPmFor24) - fudgeTZRange) /*4 for eastern */ % 24; // dtstart.getTimezoneOffset() / 60; // tzname = offsets.get(lookupTimezoneOffset); //[0]?.value; tzname = offsets.get(-lookupTzOffset24HrWithTZ + 12) !== undefined ? offsets.get(-lookupTzOffset24HrWithTZ + 12)[0]?.value : undefined; const tzflags = offsets.get(-lookupTzOffset24HrWithTZ + 12) !== undefined ? offsets .get(-lookupTzOffset24HrWithTZ + 12) .map((q) => q?.utc.map((n) => FLAGSBYTZ[n] /* ?? n*/).join("\u200B")) .join("") : undefined; return { localeStart: dtstart.toLocaleTimeString(), localeEnd: dt.toLocaleTimeString(), lookupTzOffset24HrWithTZ, tzname, tzflags, lookupTzOffset, lookupTzOffsetHr, lookupOffset24Hr, dtstart, dtend: dt }; })33:T854,calendarLink = function({ title, start, end, allDay, timezone, description, location, url, filename, lastModified, label, attributes = {} }) { // Copying so that the original values aren't modified const startDt = new Date(start); const endDt = new Date(end); const tzId = timezone || "UTC"; const zeroPad = i => i.toString().padStart(2, "0"); // Use local time (whatever it is) for all day to avoid UTC issues const formatDateTime = dt => (tzId === "UTC" && !allDay ?
