About the time in Decatur
The zone identifier America/Chicago is the value you want in code, calendars and travel systems. Abbreviations change with the season, but America/Chicago keeps pointing at Chicago time whatever the date, which is why every timestamp on this page is built from it.
Decatur sits at latitude 40.74, in the mid-latitude band, so day length here swings noticeably between midwinter and midsummer — today's 13h 29m is one point on that curve, not a fixed value.
If you are coordinating from another country, the shortcut is the working window: a normal Decatur day of 09:00–17:00 falls between 14:00–22:00 UTC. Convert your own hours into UTC once and you can tell at a glance whether someone there is likely to be at their desk.
