It looks, from online info available on school years 2015-2019, like Fiji DST
should end on the Sunday before the third Tuesday (Sunday, Monday, and Thursday
based weeks don't match) giving Jan Sun > 12 (same as updated rule Jan Sun>=13)
and begins 7 weeks earlier.
Weeks/year increments currently appear to increase the third school term from 13
to 14 weeks, rather than increasing the summer holidays from 7 to 8 weeks.
So while there is a rule for the start of DST, I don't think it can be eternally
encoded in the tzdb, but could be calculated and current rules adjusted for
Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada
