About the Salt Lake City → San José route
The route from Salt Lake City, United States to San José, Costa Rica covers roughly 4,383 kilometres in a southeast direction. At standard jet cruise speed plus a one-hour allowance for taxi, climb, and descent, a non-stop flight takes about 6 hours. Both cities sit in the northern hemisphere, so the seasonal direction of daylight (longer days in June, shorter in December) matches between origin and destination.
Salt Lake City is in the temperate zone. Day length varies by four to six hours between summer and winter, so the season of your trip materially affects available morning and evening light. San José sits within ten degrees of the equator, so day length is nearly constant year-round (about 12 hours). Sunset and sunrise stay close to 06:00 and 18:00 regardless of season.
Business-hours overlap
Standard 09:00–18:00 working hours at both ends of this route overlap by approximately 9 hours. In Salt Lake City that window runs 09:00 to 18:00; in San José it is 09:00 to 18:00. This is the realistic window for live meetings, customer calls, or pair work without forcing either end out of normal hours.
Daylight saving on this route
Only one of the two cities observes daylight saving time, so the offset between them shifts by one hour twice a year. If you have recurring meetings on this route, double-check the local time around the DST transitions (March and October/November in the northern hemisphere).
