How to use an earnings calendar so earnings season stops surprising you

Why before the open and after the close are different events

Companies do not pick release timing at random. Releasing before the open lets the regular session absorb the news with full liquidity, and it pairs naturally with a morning call, typically at 8:30 a.m. Eastern. Releasing after the close lets the company present results on an evening call, typically at 5:00 p.m. Eastern, with the regular session reacting the next morning. The timing shapes who reacts first, how much liquidity is available for the first reaction, and how long you have to read the release before the next session opens.

Time zones add a second trap. Calls are usually quoted in Eastern time for United States listings, but not always: Cboe Global Markets quotes its October 30 call at 7:30 a.m. Central, which is 8:30 a.m. Eastern, and STMicroelectronics quotes its October 29 call at 9:30 a.m. Central European Time. Convert every call time into your own time zone when you write it into your diary, and keep the original quoted time beside it so a conversion error is easy to spot.

A five step routine for earnings week

Earnings season rewards routine more than speed. The same five steps, repeated each week, catch the schedule changes and the context that a single glance at a calendar misses.

Reading the week of October 22 to October 30 as a sequence

A calendar read as a list hides the shape of the week. Read as a sequence, the nine days from October 22 to October 30, 2026, have a clear rhythm: a busy Thursday, a single-report Friday, a weekend gap, and then four heavy days that carry the bulk of the season for the companies in this table. The day-by-day notes below use only the dates, timings, and sources in the table, so they can be checked row by row.

Counted across the whole window, the shape is: five reports on October 22, one on October 23, three on October 26, seven on October 27, six on October 28, seven on October 29, and four on October 30, for 33 in total. Knowing that shape in advance is the whole point of a calendar: it tells you which days need ranking, which evenings need protecting, and which quiet days are for catching up.

How a date in this table was verified

Every date in the table comes from the StockEyes market events dataset as verified on October 22, 2026. That dataset holds 194 events in total, of which 121 are upcoming, including 66 upcoming earnings events. The 33 rows in this lesson are the subset dated October 22 to October 30, 2026. No date in the dataset is estimated by StockEyes: each event carries a cited source, and the source link on each row is the place to recheck the date.

Verification has limits, and they are worth stating plainly. A cited source can itself be a calendar listing rather than a company announcement, as with the Alphabet and Amazon rows, and a company can move a date after the dataset was verified. The source column therefore does two jobs at once: it shows where the date came from, and it shows how much weight that origin deserves. A company press release deserves more weight than a calendar listing, and a recheck the evening before the report deserves more weight than either, because it catches moves that happened after verification.

Three checks turn a calendar entry into a usable plan. First, confirm the date against the linked source, not against a second calendar that may have copied the first. Second, confirm the release timing and the call time separately, because the two are often hours apart and sometimes fall on different days, as with Invitation Homes. Third, confirm the period label, because a fiscal first quarter and a calendar third quarter can land in the same week and invite a comparison between periods that do not match. A date that passes all three checks is a date you can plan around; a date that fails any of them is a date to recheck before you rely on it.
