Phase-dependent timing and medical limits
Not medical advice. Light timing depends on circadian phase; blanket morning-light advice can shift the wrong way. Usual sleep/wake inputs do not measure Tmin or DLMO. Large shifts, sleep disorders, pregnancy, light sensitivity and medicines need a professional. Melatonin is discuss-with-doctor only; no medicine or caffeine doses are recommended.

Save on this device and back up
Add your entries, then save. You can always download your entries and backups, with or without a pass. Nothing stays on this device until you press Save; download an encrypted backup too, because a browser can clear or refuse its storage. Nobody can recover a forgotten passphrase.
A file of your inputs is not encrypted: anyone who gets it can read your health and travel details. Nothing is uploaded.

About the Jet Lag Light, Sleep & Timing Planner
Enter actual flight clocks and IANA zones, usual sleep/wake clocks, desired destination clocks and trip length. Choose advance/delay or short-trip home time with optional preflight planning. The complete timeline and calendar show actual instants in both zones, with explicit phase assumptions and medical limits. No melatonin, sedative or caffeine dose is recommended.
How to use it
- Enter actual departure/arrival clocks and zones; resolve repeated-hour choices explicitly.
- Enter actual sleep/wake clocks, trip length and optional preflight days.
- Review the unmeasured phase, chosen direction and medical applicability limits.
- Generate the complete two-zone timeline and calendar, and retain private inputs.
Sources and applicability
CDC Yellow Book discusses directional adaptation, short trips, sleep/naps/light. Eastman and Burgess’s phase method explains light before versus after the circadian minimum. A usual sleep schedule is not a measured individual phase; large shifts can adapt in the opposite direction.
Limitations
- General adult information/estimates, not medical advice, diagnosis, individual treatment or clinical validation.
- Complete original inputs and backups remain available; generated reports have separate result-key previews.
- Device storage, refused features, unsupported fonts and forgotten private phrases can prevent retention or exports; keep external encrypted backups.
Privacy
On this device: nothing is sent
All records stay on this device. No cloud record, account, shared link or provider call is created. Explicit encrypted backups use your private phrase; unencrypted transfers expose private data to recipients.
Frequently asked questions
What do I get without a pass?
Without a pass, Jet Lag Light, Sleep & Timing Planner shows initial generated rows; complete generated reports require a pass; original inputs and public safety warnings remain available. Until you unlock it, the result can’t be downloaded or copied. A Pro, Premium or Ultimate pass, a one-time payment that never renews, unlocks the full result. The pricing page lists the passes and their prices.
Should everyone seek morning light?
No. Timing depends on phase and direction; blanket morning-light advice can shift the wrong way.
What happens to ambiguous DST input?
Choose the actual earlier/later occurrence. A nonexistent clock is refused rather than guessed.
Can a short trip stay on home time?
Yes. The explicit home-time option follows CDC discussion of short trips, without forcing destination adaptation.
