public class IndependenceDay
extends AbstractObservance

Observance of Yom Ha'atzmaut — Israeli Independence Day (5 Iyar).

The natural date is 5 Iyar, but Israeli law (amended 2004) requires the observed date to be shifted when Yom Hazikaron (Memorial Day, 4 Iyar) would fall on a problematic day relative to Shabbat (Friday–Saturday) or its immediate aftermath (Sunday). The complete postponement rule based on the day of week of natural 5 Iyar:

Independence Day postponement rules

Natural 5 Iyar	Observed date
Sunday	Monday (+1) — Iyar 4 would be Shabbat
Monday	Tuesday (+1) — Iyar 4 would be Sunday (post-Shabbat)
Tuesday	Tuesday (no shift)
Wednesday	Wednesday (no shift)
Thursday	Thursday (no shift)
Friday	Thursday (−1) — Iyar 4 would be Erev Shabbat
Saturday	Thursday (−2) — 5 Iyar itself is Shabbat

This observance applies the shift internally and must be declared rollable(false) — the calendar's DateRoll must not be applied on top of this already-adjusted date.
