"Each month of the Islamic calendar commences on the birth of the new lunar
cycle. Traditionally this is based on actual observation of the
crescent (*hilal
<https://en.wiktionary.org/wiki/hilal#Noun>*) marking the end of the
previous lunar cycle and hence the previous month, thereby beginning the
new month. Consequently, each month can have 29 or 30 days depending on the
visibility of the moon, astronomical positioning of the earth and weather
conditions."

https://en.wikipedia.org/wiki/Islamic_calendar

I believe some sort of standardisation took place to accommodate electronic
calendars. I’m not familiar with the details, but I did have some coworkers
working on time algorithms in the S30 series (from the 3310 team) who had
been struggling with that problem.

I'd love to hear the full story! I googled "nokia phone adjust time
look at moon," [1] but nothing came up.
