Note that this is already a problem: This year Pesach is beginning after Chodesh HeAviv, the first month of Spring. However, according to the Julian calendar we still have some leeway, since they are 14 days behind. That assumes, of course, that we take their March 21 (our April 4) as the beginning of Spring, and not the actual equinox day.
The series is based on שערים ללוח העברי by רחמים שר שלום הכהן.

In 5727, Rabbi Rahamim Sher-Shalom published the small and important book ‘The Basics of the Hebrew Calendar’, which concisely covered the basics of the Hebrew Calendar and brought great benefit to its users; but the expansion of the circle of those interested in the subject and the increase in the level of knowledge of many of them led the author, after 17 years, to compose his great book ‘Shearim to the Hebrew Calendar’ (Netanya 5744).
This book is unique in its appearance – an album edition (x3525 cm!), 235 pages, where each page includes one topic or sub-topic in the clear and precise handwriting of the author [!], including charts and tables – all ‘handmade’! 14 detailed pages in the book (hence its name) that include many chapters on the days of migration, the basics of the calendar (including appointments and postponements), the dates and their times, The day and its parts, the homelands, the periods, comparisons between the Hebrew calendar and the other calendars, and much more.
A complete picture of all the basic knowledge necessary to understand the various topics related to the Hebrew calendar, in clear and simple language, which meets the expectations of every ‘beginner’ – and also the requirements of an ‘advanced’ who wishes to deepen and expand his knowledge on this important subject, which includes a special combination of Torah and wisdom.
The author took into account that not all students of the book want to delve deeper into the set of topics, and therefore included on the second page of each cover a summary of the material presented in the chapter, while in the body of the chapter the topics are presented in detail.
A revised and expanded new edition from 5769. The new edition that came out after 25 years is based on the good old one, with the addition of new pages and parts of pages written this time in printed letters (which highlights throughout the book the additions and changes in the new edition).
The importance of the book ‘Gates to the Hebrew Calendar’ and its usefulness to the learner, researcher and anyone interested in the Jewish calendar cannot be overstated. This is a treasure that deserves to be found in every home.

My comment on an AI panel: Most of the professionals that I?ve heard speak on this topic are pushing the joint model where the AI assists the professional with input, but the professional makes the final decisions. What?s always interested in me in this model is at what point will the professionals lose some of […]
. I was struck by the grammar of Devarim 32:50, where Hashem tells Moshe Rabenu, "Die on the mountain which you are ascending..." According to my verb lists, the very first word here, "u'moos" , is in the tzivui (imperative, command) tense. Many mitzvos are phrased in the imperative tense, such as "Sh'ma - Listen!". […]

The yeast added to ancient wines produced between 4?11% alcohol. Alcohol kills these yeast cells and prevents levels of alcohol from exceeding ~10%. […]
