What sources are used and how are they used to calculate times for Hebcal?

Enhancement request:

Currently, if several items on the settings page are selected multiple calendar entries are generated. This adds clutter to the calendar. I would like this enhancement:

If a day would have multiple calendar items, then combine them into one entry for that day.

I think that if a CSV is being generated then this might be too complicated. But you should be able to do that for an ICS (iCalendar) file, which is supported by many calendar clients.

If you do that then the Subject of the entry could be "Hebcal: <Hebrew date> [<Holiday name>].

Thank you for considering this idea and for the good product.

It would be great if--when one downloads the *.ics or *.csv for the omer days--the file would include the formulation of the omer count (i.e., היום חמשה עשר יום, שהם שני שבועות ויום אחד, לעומר.) in the Subject field.

You seem to be using a different sunset time for Jerusalem, Israel, than is commonly used here. 

I assume the difference is between observed sunset and astronomical sunset. 

1.  Can you make this an option in the future?  

2.  I tried to adjust for this by changing the offsets in minutes for candle-lighting and havdalah.  This works more or less for havdalah.  However, when I change the number of minutes before sunset for candle-lighting, your web-site changes the value back to 40.  Can you disable this annoying feature? 

Thank you. 

I downloaded a Hebrew calendar file from you site for Jerusalem, Israel, today. 

On the computer, the candle-lighting and havdalah times are close to correct. 

When I load the file into Outlook, another hour is added to the times during daylight savings time in Israel, such that candle-lighting for 27 Oct 2017 is 18:14 and candle-lighting for 03 Nov 2017 is 16:03!  Similarly, candle-lighting for 16 Mar 2018 is 17:07 and candle-lighting for 23 Mar 2018 is 19:12!  

How can this problem be solved? 

What does "Sigd" mean? It's on November 18, 2017  29th of Cheshvan, 5778 Parshas Toldos 

Hi, There seems to be a contradiction in the Calendar for 2018.  In the Calendar View for 7th April 2018, it shows the Torah Portion is Shmini, but when I click on it for more details, it says Shmini is read on 14th April.  I get the same for the 14th when clicking on Tazria-Metzora, it says it is read on 21st April.  I am looking for the Israel readings and believe this is something to do with the difference between Diaspora and Israel reading schedule.

Could you please clarify?

Many thanks!
