Zmanim Calendar Generator Supports 2007 DST Changes

Sunrise CalendarThe Java version on the server was just updated to JDK 5.0 Update 11 and now supports the US 2007 DST Changes mentioned in the previous post. This means that Excel zmanim calendars generated by this site will have the proper daylight savings time for zmanim.

Zmanim Calendar Generator Does Not Yet Support 2007 DST Changes

Sunrise CalendarAs you may know, the U.S. is changing the Daylight Saving Time rules this year due to the Energy Policy Act of 2005. The server currently hosting this site does not yet have the Java patch for this. This means that from the second Sunday in March (the 11th) until the the last Sunday in March (the 25th), calendars generated from the Zmanim Calendar Generator will show the zmanim in standard time and not daylight savings time (DST). The same issue will happen in the fall from the last Sunday in October (the 28th) till the first Sunday in November (the 4th). The Java version used by the server should be patched within the next week or 2 to the latest Java 5 (JDK 1.5) version to solve this problem.

Java Zmanim API Update

The first phase of change to allow easier porting to other languages took place with the change in the API from using inheritance of the Java Calendar classes, to one that uses composition. This will make porting it to other languages easier. Included in the update are a number of new zmanim, mostly the addition of a number of new calculations for plag that are useful when trying to avoid a tartai desasri with early erev shabbos minyanim.

Zmanim Pages Updated

The static pages for the Zmanim project have been slightly updated. The main zmanim page has been revamped, an instruction page added and some other minor changes made. One change to the main page has been the addition of the list of types of zmanim that can be calculated. One reason for this change was for search engine optimization. I ran AWStats on the log files for the last month and a half and the following search phrases brought people to the site (listed in order of popularity)
“hebrew date”, “zman krias shema”, “hebrew date php”, “kosher coffee”, “zmanim nassau”, “zman tefilah”, “time of sun in zenith calculate”, “zmanim”, “wordpress hebrew”, “elevation of sun time of day”, “harfenes”, “asia generator”, “date hebrew”, “xsd time format”, “hebrew plugin”, “plag hamincha”, “get calendar java calc”, “zmanim calendar”, “jewish zmanim”, “calendar generator”, “milliseconds xsd time”, “annual calendar generator”, “java calculate start of the day”, “calculating sun zenith angle”, “calendrical spreadsheet”, “calculate mincha gedola”, “milliseconds into minutes”, “sun s zenith”, “javadoc api “, “time formats milliseconds”, “sof zman krias shema”.
The logs also showed that many people who were searching for zmanim related searches never moved beyond the JavaDocs pages that matched their query. The technical nature of the page probably threw them off. The addition of the listing of types of zmanim will hopefully lead many searchers to the main page instead of the JavaDocs page in the future.
