Confidence score: 4/5

  • snapshots/financial/XMAD.json appears to target the Madrid Stock Exchange while the PR claims to add Tel Aviv Stock Exchange (TASE/XTAE) holidays, so the intended TASE calendar may remain unchanged or holidays could be applied to the wrong exchange — verify the target snapshot and update the file or PR metadata accordingly.

P3: The PR title ("Add tase") and description claim this adds Tel Aviv Stock Exchange (TASE/XTAE) holidays, but the changed file is snapshots/financial/XMAD.json, which is the Bolsas y Mercados Españoles (Madrid Stock Exchange) calendar. The TASE snapshot (XTAE.json) and its code/tests already exist in the repo. Clarify the PR scope: update the title/description to reflect that this is the XMAD snapshot, or if the wrong snapshot was committed, add the intended one instead.</violation>

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Add the Friday closure for Sunday holiday eves.

This branch removes every Sunday eve and skips the Friday bridge day. The stated TASE rule also applies to holiday eves. For example, Rosh Hashanah Eve is Sunday, September 9, 2029, so this code omits the Friday, September 7 closure. (hebcal.com)

Handle the known Passover II Eve half-day collision as a narrow exception. Do not exclude all eves from the Friday rule.

TASE traded normally on both dates. Delete the October 31, 2023 entry. Do not replace it with a 2024 static holiday.

Regenerate snapshots from the current bridge-day label.

TelAvivStockExchange._populate_public_holidays() adds tr("שישי לפני חג") to fri_dt. HolidayBase._add_holiday stores that label directly, so it cannot produce "Yom Kippur Eve (Friday before holiday)". With en_US, the catalog produces "Friday before a Sunday holiday". Regenerate snapshots/financial/XTAE.json.
