Notes from the time database
Context for this rule
These source notes are preserved from tzdata. They help explain a rule’s period, without adding claims beyond the source.
Summer time was in that period in 1980 and 1984, see You can of course read it in translation. I checked the local newspapers for that years. It started on midnight and end at 01.00 am. Also see this thread about the moin.gov.il URL:
