Find the best nap time, wake window and bedtime by age.
This calculator estimates the next nap, wake window, nap length, and bedtime shift. It is a planning tool, not medical advice.
SleepQuify’s nap time calculator estimates the next nap, wake window, nap duration, and bedtime adjustment using a profile-based sleep pattern. It is built for quick use without forcing you through a long sleep app flow.
Different profiles have different wake windows and nap goals. A 4 month old baby, a toddler, and an adult do not usually benefit from the same nap timing or the same nap length.
This calculator starts from the last wake time. It applies a profile-based wake window, which gives the estimated start time for the next nap.
It then estimates the nap duration and calculates how that nap may affect bedtime later in the day. Short-sleep days usually shift bedtime earlier. Easier days or longer naps can allow a slightly later bedtime.
Use this together with the SleepQuify sleep calculator if you also want a simple sleep cycle timing tool.
This gives a normal nap estimate for the selected profile and day pattern.
This is best for older kids, teens, or adults who want a shorter reset nap and do not want bedtime to drift too late.
This favors a longer nap where it makes sense for the selected profile, but it can push bedtime later.
