Bimaxion is a schedule that combines elements of Dual core and Dymaxion schedules.[1] It is designed as a transitional schedule for a gradual adaptation route to Dymaxion, as well as a fallback schedule after Dymaxion fails.


The original schedule, named "Quadphasic" was proposed by GeneralNguyen on a reddit post. After some revisions, it became its current form, with 2 short cores and 2 30-minute naps. Later, it was renamed to "Bimaxion" to match Trimaxion.


The two cores placed in the evening and morning makes it a Dual core schedule, with SWS and REM mostly being repartitioned into the first and second cores, respectively. However, unlike a shortened DC2, Bimaxion's distribution of sleeps is made to resemble Dymaxion - four sleeps equidistantly placed throughout the day, which is meant to facilliate a transition to Dymaxion. One core sleep should be placed near the SWS peak early in the morning, whereas the other core should be 6 hours later, near REM peak. Both naps are expected to provide a mixture of SWS and REM sleep, as their duration allows a significant amount of SWS to be present.


So far, all successes reported on this schedule are done cold turkey. However, most of the successful adaptations are from short sleepers. A gradual adaptation from a schedule with 30m naps (e.g, DC1 or DC2 with a 30-minute nap) may be possible, but it has not been shown to work yet.


Along with DC3 and E3, Bimaxion only has around 4 hours of total sleep. However, Bimaxion is considered more difficult to adapt to, because of the SWS wakes that appear near the end of the naps, and the SWS deprivation due to single-cycle cores. Compared to other Dual core and Everyman schedules, it can be difficult to stay awake during the relatively long night gap during adaptation.

Lifestyle Considerations

With two core sleeps to plausibly fulfill all SWS and REM sleep requirements, it is more flexible than Dymaxion after adaptation, but likely only to a small extent for most sleepers. One short sleeper has been able to make Bimaxion highly flexible as a pathway to adapt to Ducamayl.

Bimaxion only requires one daytime nap, and can fit into those with consistent daily schedules as long as a daytime nap is possible. However, the longer 30-minute nap may be slightly more difficult to schedule compared to a standard 20-minute nap. Days on Bimaxion have been anecdotally reported to feel greatly lengthened, due to the low total sleep and the absence of long sleep blocks.

The relatively early first core may pose issues for some. However, on this schedule, even after adaptation, any events that interrupt or force any of the cores to be skipped will be very damaging, and the resulting sleep deprivation may take several days to recover from.
