It dates the older castle to the reign of Imam as-Salt bin Malik al-Kharusi, 237 to 272 AH and 851 to 885 CE. ### A renewal recorded in both eras The museum says the castle was renewed during Imam Nasir bin Murshid al-Yarubi's reign in 1034 AH and 1625 CE. These are paired labels for historical context, not values to subtract as if both calendars shared a year length. ### The circular fort took nearly twelve years The museum dates the fort's construction to approximately 1066 to 1077 AH and 1656 to 1667 CE. It describes the immense circular structure as a defensive tower built for firepower. Paired dates are not a conversion formula A few historical pairs do not support deriving a constant offset between Hijri and Gregorian years. Their year lengths and month systems differ, and approximate date ranges add uncertainty. Conversion must use an appropriate calendar implementation and clear source assumptions. Local learning landscape ## A governorate centre with a broad university pathway Nizwa's educational context supports beginner, school, university and adult routes without pretending they share one level. ### Ad Dakhiliyah's administrative centre The [Oman government portal](https://gov.om/en/ad-dakhiliyah-%E2%80%8Dgovernorate) locates the governorate office in Nizwa and identifies the Wali of Nizwa among the governorate's administration. ### A non-profit university opened in 2004 [University of Nizwa](https://www.unizwa.edu.om/index.php?contentid=1&lang=en) says it was established in 2004 as a faculty-governed not-for-profit private university. Its inaugural class of 1,200 students began courses on 16 October 2004. ### Four colleges and fourteen departments The university's [schools and colleges page](https://www.unizwa.edu.om/index.php?contentid=6&lang=en) lists fourteen departments across Arts and Sciences; Economics, Management and Information Systems; Engineering and Architecture; and Pharmacy and Nursing. ### Foundation includes computing The same page says foundation courses cover English, mathematics, computing and general study skills. It lists more than twenty diplomas, more than thirty bachelor's programmes and six master's programmes. ### Computer science through several levels The [programme page](https://unizwa.edu.om/index.php?contentid=761&lang=en) lists diplomas and bachelor's degrees in Computer Science, Statistics and Mathematics, plus a Bachelor of Education in Computer Science. ### Information systems and security The university's CEMIS page lists diploma and bachelor's routes in Information Systems and Web Design and Information Security, plus a master's in Information Systems. The University of Nizwa, the National Museum, the governorate and Modern Age Coders are independent. Their pages provide verifiable local context rather than endorsement. Signature project ## The recurring date that drifts by one day The bug begins when a developer replaces the instruction next calendar month with a thirty-day duration. ### 1. Store the ambiguous rule A synthetic scheduling record contains an original date label, calendar system and instruction. The naive schema keeps only a converted timestamp and a field called repeat every 30 days. ### 2. Show the divergence Gregorian months can contain twenty-eight, twenty-nine, thirty or thirty-one days. Hijri months normally contain twenty-nine or thirty. Adding thirty elapsed days and advancing one calendar month can therefore land on different dates. ### 3. Make intent explicit The repaired schema distinguishes a duration from a calendar period, retains the calendar identifier and original label, applies a documented end-of-month policy and tests round-trip conversion. | User intention | Stored operation | Needed metadata | Invalid shortcut | | --- | --- | --- | --- | | Thirty elapsed days later | Duration of 30 days | Instant or local date and timezone rule | Calling it next month | | Same day next Gregorian month | Gregorian calendar period of 1 month | Calendar and end-of-month policy | Adding 30 days | | Same day next Hijri month | Hijri calendar period of 1 month | Calendar variant and authority | Assuming every month has 30 days | | Official observance date | Reference an official announcement | Source, jurisdiction and verification date | Publishing a generated prediction as official | ### Conversion and authority are separate questions A library can implement a calculated calendar, but software output does not replace an official announcement where observance depends on an authorised process. The interface must state what it calculated and where an official value came from. Calendar-aware design ## Preserve four pieces of information Calendar arithmetic becomes testable when the data model stops treating every date as an unlabeled string. | Field | Purpose | Failure if omitted | Example type | | --- | --- | --- | --- | | Original label | Preserve source wording | Round-trip cannot be audited | Text | | Calendar identifier | Choose rules for year and month | Arithmetic uses the wrong system | Controlled code | | Normalized civil date | Sort and integrate consistently | Chronology becomes string-based | ISO local date | | Authority and status | Distinguish calculated from official | Prediction presented as announcement | Source URL and status enum | | Operation intent | Separate duration from period | Recurring events drift | Duration or calendar-period type | ### For children Two physical calendars show unequal months. Learners move one month and thirty spaces as different operations. ### For teenagers Python tests cover leap years, short months, invalid input and explicit calendar identifiers. ### For university and adults APIs, databases and audit logs keep conversions, sources and business rules consistent across services. The scheduling records are synthetic. Historical Nizwa date pairs remain cited source evidence and are not altered to make a coding example work. Source QA ## Historical ranges need uncertainty fields too The museum's approximate paired ranges show why a parser must not manufacture precision. ### Ranges are not exact instants The fort's approximately 1066 to 1077 AH and 1656 to 1667 CE ranges belong in start and end fields with an approximation flag. ### Reign ranges are context The castle date 237 to 272 AH and 851 to 885 CE describes a ruler's period in the source, not a precise construction day. ### Display both without fake arithmetic A heritage interface can show both source labels while using normalized fields only for operations that the evidence supports.

Submitted details are used for placement and follow-up. FAQ ## Nizwa coding class questions The answers separate historical source data, calculated calendars and official announcements. ### Can University of Nizwa students join these classes? Yes. University learners can request computer science, Python, databases, web development, data analysis, mathematics or another suitable route, subject to placement and teacher availability. The University of Nizwa and Modern Age Coders are independent organisations. A free class identifies the learner's current level and a practical next project. ### Can children and teenagers in Nizwa enrol? Yes. Modern Age Coders teaches ages 6 to 67. A child or teenager completes a free ability-matched task before placement. The teacher considers logic, typing, mathematical fluency, debugging and explanation. School name and grade provide context but do not automatically determine the course or class level. ### What is the Nizwa dual-calendar coding project? The learner models Gregorian and Hijri dates as calendar-aware values. A naive program treats one month as thirty days and silently shifts recurring dates. The repair stores the calendar system, parses the original label, uses a tested calendar library for conversion, applies month arithmetic in the intended calendar and preserves the source text for audit. ### Does the project predict religious dates? No. It is a software and data-modelling exercise, not an authority for observance dates. Official announcements must be used where required. The project explains that calculated calendars, local observation and published civil dates can have different roles. Learners must not present generated output as an official Oman calendar. ### Does Modern Age Coders have a Nizwa centre? No Nizwa office or classroom is claimed. Lessons are live online. A learner joins with a laptop or desktop, stable internet, audio and a current browser. The teacher interacts synchronously through explanation, screen sharing, coding and review. This page describes service availability for Nizwa rather than a physical branch. ### Why is adding thirty days not the same as adding one month? Calendar months do not all have thirty days. Gregorian months vary between twenty-eight and thirty-one days, and Hijri months normally have twenty-nine or thirty. Month addition also needs a rule when the target month lacks the original day number. Duration arithmetic and calendar arithmetic therefore answer different questions. ### How much do Nizwa coding classes cost? The first class is free. Standard group tuition is USD 100 per month for two live lessons each week, normally eight lessons monthly. Standard private tuition is USD 150 per month for one learner with one teacher on the same usual frequency. Course, class format, recurring time and availability are confirmed before payment. ### What is the class size for Nizwa learners? A group normally contains five to eight compatible learners. Compatibility considers present skill, pace and objective rather than age alone. Private tuition is one learner with one teacher. If no suitable group is available, the learner can discuss private tuition or wait for an appropriate cohort. ### How are Nizwa class times arranged? Oman is one and a half hours behind India. The learner and teacher agree a recurring time before payment, generally for two live lessons each week. Friday and Saturday options may be discussed subject to availability. School or university examinations, adult work and Ramadan routines should be mentioned before confirmation. ### What happens in the free Nizwa class? The teacher asks about the learner's objective and observes a short task suited to the stated level. A child may compare calendar cards, a teenager may repair date arithmetic in Python, and an experienced learner may design a calendar-aware database schema. The teacher then explains the suggested course, format, timing and USD fee. The first class requires no tuition payment.
