The Zmanim Calendar Generator has been back up for about 2 weeks, but due to a downgrade in the Java version used, the DST issue that was as mentioned as fixed in a previous post returned. This has now been fixed using the Timezone Updater Tool. Please let me know if you run into any […]

The Zmanim Calendar Generator is temporarily out of commission due to technical issues being experienced by my web hosting company. My web hosting company was bought out and the new company experienced technical issues in the migration, including Java issues that affect the calendar generation. They have no ETA for a fix.

A user contacted me with the following note (some details removed).

This will make porting it to other languages easier. Included in the update are a number of new zmanim, mostly the addition […]

I hope to have an update available for the Zmanim API that will allow easier porting to different languages. This will necessitate changing the API from using inheritance of […]

To use this feature, click on the Google Maps icon to display the map (location centered on Bais Medrash Gevoha in Lakewood), find the location that you want to generate zmanim for, and click […]

The Zmanim API currently has 2 sample classes in the output package. One outputs zmanim as an Excel spreadsheet and is currently used in the Zmanim Calendar Generator, the other that is not fully maintained outputs zmanim in a PDF format. I just started work on the third output class. This will generate an RSS […]

I slightly updated the Zmanim Calendar Generator to add some user input validation.
Looking at the logs, I noticed that someone generated a calendar with the longitude and latitude of Lakewood, NJ (the default), with just the location label changed to Minneapolis, MN. I don’t know if the user was just testing, or just assumed that […]
