Dual Core 1, or DC1, is the first [[Dual core|Dual Core]] schedule, which is the result of cutting some sleep from the second core of Segmented and the addition of one daytime nap to compensate.<ref name="polysoc" /> DC1 is also considered a relatively easy schedule, and is often recommended to beginners.

Currently, the standard variant is recommended to have a core sleep of 3h20m and 1h40m respectively. The cycle length being a multiple of 100m instead of 90m is meant to accommodate either longer sleep cycles, or extra [[wikipedia:Rapid_eye_movement_sleep|REM]] at the start or the end of the sleeps.

The nap is placed around the circadian dip in the early afternoon. However, the nap on DC1 is not always filled with REM sleep and may contain mostly NREM2 for some. Nevertheless, the nap helps [[wake time reduction|sustain alertness]] until core 1.

DC1 is often compared to [[E2]], as both schedules has sleeps placed at similar times of day. They have a similar amount of total sleep and the same number of sleep blocks (3) per day, with the main difference being E2 having a dawn nap rather than a dawn core on DC1.
