Frequently Asked Questions
The calculator uses a simple rule of thumb: for eastward travel, recovery takes about 1 day per time zone crossed; for westward travel, about 0.5 day per time zone.
The calculator accepts up to 24 time zones. For extreme crossings, recovery may vary, but the formula still provides a rough estimate.
Traveling eastward requires your body to adjust to an earlier time, which is generally harder than adjusting to a later time when traveling westward, hence the difference in recovery days.
