AC doesn’t calculate charts for Israel 1980, 1984 for DST (Daylight Saving Time) correctly.

Time Changes in Tel Aviv Over the Years

Daylight Saving Time (DST) changes do not necessarily occur on the same date every year.

Extract

In the past, the unpredictability of IDT in Israel became frustrating enough that Microsoft Windows stopped trying to track changes and just made Israeli time be Greenwich Mean Time plus two hours (GMT+2) (and disabled the daylight saving option). This led to various ad hoc solutions to the problem in Windows systems and other Microsoft software (e.g. Outlook calendar entries were often off by an hour when shared, due to the lack of IDT support).

New York DTS

Transit Chart – One minute prior to the DST Change-Over (Clocks go forward one hour at 2:00am so local time is 3:00 am for the change-over). Still EST.

The Change-Over to EDT: 3:00am local time

DTS Change-Over

Notes:

In fact the chart for 2:59 am is in reality 3:59 am because the time of 2:59 is ambiguous and doesn’t really exists because the clocks went forward one hour at 2:00 am to 3:00 am. This is the same approach to the problem that astro.com implements.
