For a tutorial on how to establish the Jewish calendar, see the video linked below - or a PowerPoint with the same information for 5784 at https://docs.google.com/presentation/d/1VjDan_Titibc7bOJiYZkSZywhreEG9DJ/edit?usp=sharing&ouid=108360675515039678488&rtpof=true&sd=true
For a set of useful apps for the Jewish calendar, download the folder at https://drive.google.com/open?id=12uFNnNUg3Fk_Q6YWPWabNdV0yMuyx65b.Â
To use it, download the zip folder, check for viruses, and unzip.
Along with supporting files, the folder contains two html pages.
The two html pages are tools to aid the presentation below.
The first is Calculator.htm, for calculating the molad.
The second is Keviyus.htm, which is a web page equivalent of the 14 keviyuyos chart in the Tur Orach Chaim 428. It shows every detail of the 14 different Jewish calendars, along with some convenient aids to visualization.
The main presentation is This year's calendar. It walks through the process of creating a calendar in detail, from beginning to end. The youtube video for that presentation is at https://www.youtube.com/channel/UC8L25iBp_ZUias3gnvtFJTA. It is for the year 5780.
