This is most unusual. It is a rare occurrence for four lunar cycles on successive Passover and the Feast of Tabernacles (Sukkot) observances. It will not happen again for hundreds of years.
Four lunar eclipses occurring on the Feast of Tabernacles and Passover in two successive years are phenomenal. But add to them two solar eclipses on the two days that open the Jewish year - Adar 29/Nisan1, just two weeks before Passover, and Tishri 1 (Rosh Hashanah) - is uncanny. On each of these six Jewish Holy Days, the sun will be darkened and the moon will not give her light. Will this happen again in the 21st century? No. Did it happen in the 20th century? Yes, in 1949/1950, the year following Israel's statehood, and 1967/1968, the year Jerusalem was liberated in the Six-Day War! Before that, you have to go back to 1493 for four successive lunar eclipses on Passover and the Feast of Tabernacles.
