Competition identity
A daily list is organized by court and sequence
A tennis order of play tells you which matches are intended for each court and their order. It is different from a season calendar, a tournament draw or a broadcaster’s programme listing. Wimbledon’s official schedule supplies the daily order, while its visitor information explains that the next day’s list is published the previous evening.
An early ticket or a general tournament date therefore cannot guarantee one particular match on one court. For viewing, begin with the actual daily list rather than assuming a seeded player will appear in the same session throughout the tournament.
Earlier matches affect the later ones
A tennis match does not have a fixed playing duration. A short straight-set contest and a long match with extended sets occupy different amounts of court time. A match listed after another cannot ordinarily begin on that court before the preceding match has finished and the court is ready.
This makes a later match different from a football fixture with its own separately scheduled kickoff. A projected television time can be useful for planning, but it should not be described as an unconditional promise that the first ball will be struck then.
Read not-before as a lower bound
A not-before label means the match is not intended to start earlier than that time. It does not mean it must start exactly then if earlier play or other conditions delay the court. Keep the label with the time when copying it into your own viewing list.
In a hypothetical schedule, a match is second on court and not before 15:00. If the first match is still running at 15:20, the label has not been contradicted. It prevented an earlier start; it did not guarantee the previous contest’s finishing time.
A session and one match can have different scopes
A tournament session can contain several matches. A broadcaster may cover a main court, switch between courts or offer separate court feeds, depending on its actual service. A generic tournament programme title does not establish continuous coverage of one selected player.
Write down the court and round beside the player names. If the viewer’s priority is a doubles match on an outside court, a main-court session may be the wrong programme even though both listings carry the same tournament logo.
Keep the organizer’s time and your date together
A court schedule is tied to the event’s local time. Your programme guide may display a converted time. Cross-midnight differences and daylight-saving rules can change the displayed date as well as the hour. Retain the original date and zone when making the conversion.
For a replay, use the actual match date, players and court rather than only the planned start time. A delayed match can appear in a later programme window. That identification solves a different problem from checking whether a service offers the requested live or replay coverage.
Questions answered
Does not before mean exactly at that time?
No. It is a lower bound, and later conditions can delay the start.
Is the draw the same as the daily order of play?
No. The draw shows the tournament path; the daily order assigns matches to courts and sequence.
Does a tournament programme guarantee every court?
No. The actual programme or service description determines its coverage scope.
