Chicago Library Events: 4,875 Sessions, 96.5% Of Them Before January

The Chicago Public Library’s public calendar holds 4,875 scheduled sessions, and 4,704 of them — 96.5 percent — happen before January. The furthest date listed is July 22, 2027, but the volume falls away long before that: 1,793 sessions in October, 35 in January. That is a measure of how far ahead branches post, not of what the library will do in the new year.

Chicago Public Library Events (vsdy-d8k7), 4,875 scheduled sessions at 106 named locations, start times September 16, 2026 through July 22, 2027, retrieved and last updated September 16, 2026, read whole · a forward calendar: the file’s own description says “Only events that have not yet occurred are shown,” so every count here is what was scheduled that day, never what happened · event titles and descriptions were never read, so no author, performer or presenter is named · type, audience and language values are the file’s own labels · the file records no attendance, cost or capacity

The calendar thins sharply after December

Every month in the file. September 2026 begins at the retrieval date, September 16.

October is the peak at 1,793 sessions, and the drop after December is a cliff rather than a slope: 693 sessions in December, 35 in January, 31 in February. The 171 sessions dated in 2027 are 3.5 percent of the file. A forward-only calendar cannot show what January will hold — only what was already posted for it on September 16 — and on that day the library had posted its autumn and barely begun its winter.

Three entries in four are one date of a repeating series

3,732 of the 4,875 sessions, 76.6 percent, carry the file’s recurring flag, and each dated session is its own row rather than one row for a whole series: 298 combinations of branch, weekday and clock time recur on four or more separate dates in the file. That is what makes 4,875 a count of sessions and not of programs. Beyond recurrence the file flags two other things: 63 sessions already marked cancelled, and 71 marked featured. As for length, 1,950 sessions — 40.0 percent — are scheduled for exactly an hour, and 1,607, a third of the calendar, run two hours or longer.

Who the sessions are for

A session can carry several audience labels, so these do not sum to 4,875: 2,433 sessions carry one label, and six carry all eight.
Audience label, youngest to oldest	Sessions	Share of sessions
Babies	684	14.0%
Toddlers	841	17.3%
Preschoolers	1,054	21.6%
Kids	1,062	21.8%
Tweens	725	14.9%
Teens	1,513	31.0%
Adults	2,273	46.6%
Seniors	644	13.2%

Adults are named on 2,273 sessions and teens on 1,513 — the two largest audiences, ahead of every label for a child; seniors are named least often, on 644. The labels overlap by design — 2,442 sessions carry two or more — and a session labeled for babies, toddlers and preschoolers at once is a single story time, not three.

Most of it happens before five o’clock

3,829 sessions, 78.5 percent, start before 5 p.m.; 437 start at 5; and 609, one in eight, start at 6 p.m. or later. The single busiest hour is 10 a.m., with 767 sessions. The daytime pattern holds for grown-ups too: of the 1,284 sessions labeled for adults and no other audience, 371 — 28.9 percent — start at 6 p.m. or later, so seven in ten begin earlier, and 317, 24.7 percent, fall on a Saturday or Sunday, leaving three-quarters on a weekday. By day of the week, Thursday leads with 1,017 sessions and Tuesday follows with 935, while Friday holds 425 and Sunday 207, fewer than any weekday.

Six languages, and two of them carry nearly everything

English is listed on 4,806 sessions and Spanish on 497; the rest of the file’s languages are Chinese (Simplified) on 14, Korean on 8, Arabic on 3 and Russian on 3. Read as sets, 4,361 sessions — 89.5 percent — list English alone, 425 list English and Spanish together, and 67 list Spanish alone. That leaves 514 sessions, 10.5 percent of the calendar, listing any language other than English. Spanish is on 497 of those 514; the other 17 list Chinese (Simplified) or Korean.

What the sessions are called

The twelve most common of the file’s 22 type labels. A session can carry several; 4,299 carry exactly one.
Type label	Sessions
Crafts, Games and Play	1,979
Story Time	858
Continuing Education and College	383
Book Clubs	324
Health and Science	323
Computers and Technology	312
Workshops	277
DIY	266
Film Screenings	264
Art, Music and Performances	190
Writing and Poetry	101
Celebrations	48

Crafts, Games and Play is on 1,979 sessions and Story Time on 858; because a session can carry both, the two together cover 2,790 distinct sessions — 57.2 percent of the calendar. The labels are the library’s own, and they describe how a session is filed, not what it is worth: Continuing Education and College, Book Clubs, Health and Science and Computers and Technology each appear on between 312 and 383.

Where the sessions are

All 4,875 sessions by the location named on them.
Location label	Sessions
Harold Washington Library Center	242
Chicago Bee	223
Sulzer Regional	222
Lincoln Park	129
Rogers Park	123
Gage Park	122
West Loop	115
Little Village	114
Wrightwood-Ashburn	113
Woodson Regional	96
The other 96 named locations	3,220
No location label at all	156

The Harold Washington Library Center, the system’s busiest building by visits, also posts the most sessions, 242, with Chicago Bee at 223 and Sulzer Regional at 222 close behind. Concentration is mild: the ten busiest labels hold 30.7 percent of the calendar, and 14 named locations list exactly one session each. The 106 values are the file’s own location labels, which it does not classify, so they need not correspond one to one with branch buildings. The 156 sessions with no location label carry no zip code and no location detail either, and 141 of them have a registration window open or upcoming — what kind of session they are, the columns read here do not say.

Registration is the exception, and cost is not a column

3,423 sessions, 70.2 percent, are filed NOT REQUIRED for registration; 1,295 are open for registration now, 127 have a registration window that has not opened, and 30 have one that has closed. Cost is a different matter: this file has no price column at all, so nothing here says whether a session is free — a contrast with the Park District’s activities file, which lists a fee on every program.

What the calendar confirms, and what it cannot tell you

Confirmed, as scheduled on September 16, 2026: each session’s start and end, its location label, its type, audience and language labels, its recurrence and cancellation flags and its registration window. What no column read here holds: attendance, capacity, cost, who leads a session, or whether it took place. Because the file drops events once they have occurred, it also cannot be used to count what the library ran last month — the branch-level 2026 ledgers are the files that count that.

Where the record lives

The library events file sits on the city’s data portal and was itself updated on September 16, 2026. Every figure here was computed from the calendar as it stood that day; because the file drops events as they occur and gains them as branches post, a later pull will not reproduce these totals.

The bottom line

Asked what the library has planned, the calendar answers: 4,875 sessions, 96.5 percent of them before January, three in four of them one date in a repeating series, seven in ten needing no registration, and 78.5 percent starting before 5 p.m. Adults are the most frequently named audience, English the only language listed on nine sessions in ten, and Harold Washington the busiest of 106 location labels. What any session drew, the file does not record.

Two more questions the calendar can answer

How long is a session? The median is 60 minutes, the shortest 30 and the longest 1,439 — a full day minus a minute. And how much of the calendar is already off? 63 sessions carry the cancelled flag, 59 of them dates in recurring series, which is 1.3 percent of everything posted.

Forward-only: the file’s description says only events that have not yet occurred are shown, so every count is what was scheduled on the retrieval date. Nothing here is a count of what happened.
Columns read: event id, type, audience and language labels, location name and zip, start and end, day of the week, the recurring, cancelled and featured flags, and the registration fields. Titles, descriptions, event links, street addresses and coordinates were never selected, so no person is named here.
Labels: type, audience and language values come pipe-separated in the file and are counted once per session, so those tables do not sum to 4,875. They are the library’s labels, not our judgments about a session.
Sessions, not programs: one row is one dated session; 298 combinations of branch, weekday and clock time recur on four or more dates, which is how a weekly series appears.
Not here: no attendance, cost or capacity, none of which the file records, and no judgment of any branch or session.
