How do interruptions and an innings change alter the minimum overs in an MCC match’s Last hour?
Under Law 12.6, when one hour of Playing time remains according to the agreed hours of play, the over in progress is completed. The following over starts the minimum 20 overs that must be bowled if no result is reached earlier and there is no interval or interruption in play; the period thereafter is called the Last hour, whatever its actual duration. For each interruption during that period, deduct one over for every complete three minutes lost, calculated separately for that interruption. If an innings ends after the Last hour has started and a new innings is to begin, compare the remaining-overs and remaining-time calculations and use the larger, subject to the interval rules.

The Last hour begins at a Playing-time point
The one-hour mark is measured against the agreed hours of play, not by counting back exactly 60 elapsed minutes on a wall clock. The over in progress at that point is completed. The Laws call the period after the 20-over minimum begins the Last hour; its actual duration can exceed 60 elapsed minutes when play time is lost. The following over starts the indicated minimum of 20, if no result has already been reached and no interval or interruption is under way.
For an ordinary interruption, lost time runs from the call of Time until the resumption time fixed by the umpires. Deduct one over for each complete three-minute block in that interruption. If there are several interruptions, work them out one at a time; do not add short breaks together to make a block.
An interruption crossing the start has its own over rule
If an interruption is already under way at the one-hour Playing-time mark, count only the later time lost after that point. The over interrupted before the Last hour is completed when play resumes but stays outside the minimum-overs count.
If an over is interrupted after the Last hour has started, complete it when play resumes. Its two parts together count as one over toward the minimum, not zero or two. If a bowler cannot complete an over during the Last hour, Law 12.11 refers to Law 17.8 and its separate parts still count as one minimum over; replacement eligibility is outside this guide.
A new innings after the start uses the larger of two counts
The interval between innings is 10 minutes. If an innings interval is already in progress at the start of the Last hour, use the calculations in Law 12.7 to determine the new innings minimum. Separately, when an innings ends after the Last hour has started and a new innings is to begin, make both Law 12.8 calculations and use the larger result: round any fraction of the remaining minimum overs up to a whole over, then deduct three overs for the interval; and subtract 10 minutes from the time remaining to the agreed close, counting one over for each complete three-minute block and one for any remaining part of three minutes. The larger result is the minimum for the new innings.
Check the no-further-play and interval provisions before applying that comparison. If an innings ends with 10 minutes or less before the agreed close, there is no further play that day. For a declaration or forfeiture during an interruption longer than 10 minutes, the innings interval is absorbed if at least 10 minutes remain; if less remains, the new innings starts 10 minutes after the decision. If a declaration or forfeiture occurs during an interval other than drinks, at least 10 minutes remaining absorbs the innings interval; otherwise extend that interval so the new innings starts 10 minutes after the decision.
Meal overlaps and the conclusion rules still apply
When an innings ends within 10 minutes of lunch or 30 minutes of tea, that meal interval is taken immediately for its agreed duration and includes the innings interval. If the 10-minute innings interval is already running when 30 minutes remain before tea, play resumes at the end of that 10 minutes if conditions permit. Drinks intervals are not taken in the Last hour. These branches prevent a second generic 10-minute deduction from being added to an interval already covering it.
A match does not necessarily stop at the instant the minimum is reached. Unless an earlier result applies, the ordinary endpoint requires both the minimum overs and the agreed close; a completed final innings under a 13.1.2 agreement and the Laws’ separate no-further-play conclusion are distinct endpoints. If the minimum is completed before the original close, another over may start. The over in progress at final close is generally completed unless a result or players leaving the field ends play; the separate 16.9 scoring-error rule is not explained here.
When officials apply Law 16.3.3, lost Playing time is counted from the call of Time to the call of Play, excluding intervals (Law 11) and suspensions of play (Law 2.8). The close of play that day is extended by that amount; no overs are deducted during the Last hour solely on account of this time. This guide treats the officials’ classification as an input and does not determine whether a particular delay qualifies.
Two interruption patterns and an innings-change calculation
In an anonymous fictional match, the umpires have fixed the hours and timepiece, the roles are lawful, no result is reached early, no meal interval remains, and play resumes normally after each stipulated non-medical interruption. Two separate two-minute interruptions each deduct zero overs because neither contains a complete three-minute block; they are not pooled into four minutes. A separate seven-minute interruption deducts two overs. In a second fictional match, an innings ends after the Last hour has started with 12 whole overs plus four valid balls still unbowled in the minimum, and 41 minutes remain until the agreed close. More than 10 minutes remains and no interval or interruption overlaps the new innings interval. The overs calculation rounds 12 overs and four balls up to 13, then subtracts three to give 10. The time calculation subtracts 10 minutes from 41, leaving 31, which rounds up to 11 three-minute blocks. The new innings therefore has an 11-over minimum, subject to an earlier result and the other stated conclusion rules. No weather or participant-replacement judgment is implied.
