Nap Schedule
Build a two-nap day from a wake time and wake window length.
About Nap Schedule
The first nap starts after the wake window from waking, then each subsequent nap is placed after the next wake window, wrapping past midnight when needed. Following wake windows rather than the clock keeps naps aligned with the baby's biological rhythm and their sleep pressure.
Formula
Nap Schedule
Nap start = end of prior sleep + wake window (24-hour wrap)
- wake window
- Awake time a baby can comfortably tolerate

Assumptions and limits
- The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
