Tell us about yourself!
To start from Nissan is not common. Although is the first month in the Tanakh, Tishrei is considered as the first month in everyday life.The display is very small, you can't write such long month name string without scrolling.You could also argue for the year, it is common writing it in letters, not in numbers. But this display doesn't have Hebrew fonts.I'm Jewish myself, so the design and engineering for an acceptable and readable solution were part of the process. It takes a little getting used to, but I think the result is readable.
For the date conversion I found a ready library, so I didn't get into the technicalities of the process.The standard format I used is straight forward: it would show 14/7/5780.The only complication is for leap years, in which case Adar aleph is 6A and Adar bet is 6B. In such way all other months keep their numbers in leap years.
