About This Time Conversion

This page converts the local time between Chicago, United States (timezone America/Chicago, currently --5, GMT-5) and Ljubljana, Slovenia (timezone Europe/Ljubljana, currently ++2, GMT+2). TZSync uses the IANA timezone database so conversions always account for Daylight Saving Time, half-hour offsets such as India (UTC+5:30), and quarter-hour offsets such as Nepal (UTC+5:45).

When it is daytime in Chicago, the clock in Ljubljana reads a different hour, and possibly a different calendar day. Drag the time slider on this page to find an overlap where both cities are inside typical working hours (9 AM – 5 PM local time) — that overlap is your best window for meetings, calls, and collaboration between Chicago and Ljubljana.
