They rarely do coincide, of course. This year they were only a day apart (Pesach on 16th April, Easter on 17th April) but last year they were several days adrift (Pesach on 28th March,  Easter on 4th April). In 2016, Easter Sunday was 27th March but Pesach didn’t begin until 23rd April, presumably because the Hebrew calendar had an intercalary month added to it.

Chag Sameach Shavuot.

For whom it  concerns, the first day of the Festival of  Shavuot is Sunday 5th June next. Erev Shavuot is Saturday evening, and Yiskor on day two, Monday; I wish you a Happy Shavuot.

We are told to eat dairy foods; cheesecake is a favorite.

The term Pentecost is derived from the Greek, as for us,  it is the end of the 50 days of counting from the Passover, called the Counting of the Omer. It appears to have the same significance in this respect as the Christian holiday of Pentecost, counting 50 days from Easter Sunday.  It is also what used to be called " Whitsun." (from Wiki.)

If Easter coincides with the Passover (Pesach), then there is synchronism in these dates, but this is not always the case.

These little bits of information you share are very interesting, Jack. It reminds me of my 3rd Year in Grammar School, when the Religious Education year covered Comparative religions. We did actually get to visit a synagogue. As a girl, I got to sit in the upper ladies' gallery. It's just occurred to me it's nearly 50 years ago

I love dairy foods. They make up a fair share of my shopping trolley. Both OH and I might have been mice in a past life, the amount of cheese we eat.

Happy Shavuot back to you and yours, for Sunday.
