This project was largely created using Cursor as an experiment to see how agent coding utilities perform at understanding and implementing a specification unguided. There are no guarantees as to the accuracy of this output.

This refers to the next working Gas Day in England following the date of the report. In a report published on Friday, Day-ahead would normally apply to the following Monday, provided that Monday is not a public holiday. In this case, Day-ahead would refer to the next working day, that is Tuesday.
This covers the first Saturday and Sunday following the date of the report. Other contiguous non-working days – typically Bank Holiday Mondays and Good Friday – will be added to the contract to create a three- or four-day delivery period.
When Christmas Day and Boxing Day (25-26 December) and New Year’s Day (1 January) fall mid-week these shall be considered additional Weekend delivery periods. For example, if 25-26 December fall on a Tuesday and Wednesday, the Weekend contract quoted on the Monday of the same week would refer to Tuesday and Wednesday. The weekend after 25-26 December would be assessed as a contract for the first time on 27 December.
The contract covers the Working Days Next Week period to be delivered on every working day in the week following the date of the report. Typically this covers the five days following the next Weekend contract. In the case of a three-day weekend covering Saturday to Monday, Monday would be excluded from the WDNW contract, which would instead cover Tuesday-Friday.
Similarly, in the case where Christmas Day and Boxing Day (25-26 December) fall on a Tuesday and Wednesday, the WDNW contract assessed on the previous Friday (21 December) will refer only to the following Monday (24 December). The WDNW contract assessed on Monday (24 December) will refer to Thursday and Friday (27-28 December) only.
Balance-of-month is for delivery on each of the remaining days of the current month, excluding the next Day-ahead or Weekend contract, whichever is the sooner.
For example, on a Thursday, BOM would normally apply from the following Saturday to the end of the month (remaining days of the month minus Day-ahead). On a Friday, BOM would normally apply from the following Monday to the end of the month (remaining days of the month minus Weekend).
Should the next Day-ahead or Weekend contract cover the last day or days of the current month, the delivery period to which BOM applies will switch to the next month. Should the next Day-ahead or Weekend contract cover the first day or days of the next month, BOM will apply to the subsequent days of that month.
