Documentation:
Our code is really cool We used scratch which is a great user friendly thing. ALl you need is a web browser and boom.
Our code works by firstly finding how many days between June 19th of the year they input and Jan 1st of 1800. We Mod this day by how many days are in the lunar cycle and then add days to find the Tangaroa period. We then find the closest Friday based on this date.
We worked great as a team and collaborated well, sharing the work evenly. Since we used scratch it was difficult to collaborate on the work as only one person could edit the code at a time. So instead what we did was hop on a discord call, screen share, and then talk to each other about our ideas on how we could change/improve the code. It wasn’t easy to find times when we could all work on it in the holidays, however after the holidays, we got cracking and together we managed to produce a functional scratch program.

^Method for finding the date of the Matariki Public holiday (always on a friday)
Lunar month of pipiri (~ June) There are either 12 months, each lasting 29.53 days or 13 months made up of 28 days Tangaroa period (23rd, 24th, 25th, and 26th night) Closest friday
The Matariki holiday always lands on a friday in either late june or early july, there is seemingly no correlation between these dates
We can’t use the 13 months of 28 days because It just wouldn’t work, trust me bro
The tangaroa lunar period DOES seem to have a correlation, we firstly need to find this correlation and create an algorithm to find it.
Looks like it repeats every 11 years however is slightly thrown off by leap days as well as the last day of the year (because 365 isn’t a multiple of 7)
For a year we can use 365.25 days, if its a decimal place we round down. (This doesn’t account for not having leap years every 100 years - exception every 400 years -)
Latest 21st of july Earliest 19th of June
384 days between the first day of the Tangaroa lunar period 2022 and 2023 # 355 days between the first day of the Tangaroa lunar period 2023 and 2024 * 355 days between the first day of the Tangaroa lunar period 2024 and 2025 * 384 days between the first day of the Tangaroa lunar period 2025 and 2026 # 354 days between the first day of the Tangaroa lunar period 2026 and 2027 * 384 days between the first day of the Tangaroa lunar period 2027 and 2028 # 354 days between the first day of the Tangaroa lunar period 2028 and 2029 * 354 days between the first day of the Tangaroa lunar period 2029 and 2030 * 383 days between the first day of the Tangaroa lunar period 2030 and 2031 # 355 days between the first day of the Tangaroa lunar period 2031 and 2032 * 355 days between the first day of the Tangaroa lunar period 2032 and 2033 * 384 days between the first day of the Tangaroa lunar period 2033 and 2034 # 355 days between the first day of the Tangaroa lunar period 2034 and 2035 * 384 days between the first day of the Tangaroa lunar period 2035 and 2036 # 354 days between the first day of the Tangaroa lunar period 2036 and 2037 * 354 days between the first day of the Tangaroa lunar period 2037 and 2038 * 383 days between the first day of the Tangaroa lunar period 2038 and 2039 # 354 days between the first day of the Tangaroa lunar period 2039 and 2040 * 385 days between the first day of the Tangaroa lunar period 2040 and 2041 # …

Starting from 1 as January 1st 0000 June 19th is the 169th day of the year (170th on a leap year)
Psuedocode planning (very small)
DECLARE Year : INTEGER DECLARE TotalDays : INTEGER DECLARE LeapDays : INTEGER
INPUT “Input a year”, Year LeapDays ← Year / 4
Total Days ← Year x 365
The rising of Matariki in the morning sky is observed in the month of Pipiri (around June and July). Māori wait until the lunar phase of Tangaroa, the last quarter phase of the moon
