Hi, thanks for using the Hebcal JavaScript library.
Zmanim, Candle-lighting and Havdalah times are derived from sunset times, which are approximated from a location (latitude, longitude) and day of year. There is no way to include elevation in the Hebcal zmanim calculations because the underlying solar calculation algorithm doesn't use elevation.
The NOAA solar algorithm claims accuracy within 2 minutes except at extreme northern or southern latitudes. Adding elevation often changes the sunset calculation by 1 minute or less, so this is within the expected margin of error.
Thanks for using Hebcal!
To create a calendar with Israeli schedule, visit our custom calendar page at https://www.hebcal.com/hebcal and choose the "Israel holiday schedule" option instead of Diaspora, and make sure Rosh Chodesh is checked.
To enable alerts for Rosh Chodesh and other holidays, download/subscribe to the Hebcal calendar in your favorite calendar app. Go to the app settings and enable the option to alert on all-day/untimed events (see below for an example from the Apple calendar; there are similar settings in Outlook, Google Calendar, and other calendar apps).
Hi, thanks for using Hebcal. We double-checked and the triennial divisions as published are indeed correct. The third triennial aliyah should be 1:8-10.
Our triennial aliyot divisions correspond with both the CJLS triennial divisions and the traditional full kriyah aliyot divions (the first full kriyah aliyah ends at verse 10).
For an explanation for why the aliyah concludes with verse 10, see below excerpt from the 5783 Luah Hashanah by Rabbi Miles Cohen (highlighting mine)
Hi, thanks for your message.
We were not aware of a UK Reform triennial cycle before you alerted us to its existence. Thanks for letting us know about it! We added a brief note to the Hebcal triennial Torah reading FAQ page indicating that this resource is available.
At the current time, it looks like it would be difficult for Hebcal to display the UK Reform cycle as an alternative. To enable that, we would need a more complete cycle published. Currently we see only two different 3-year cycles (5782-5784 and 5785–5787) published on the reformjudaism.org.uk website.
When you consider the variations of Vayakhel-Pekudei, Tazria-Metzora and other parshiyot being read together or separately in any given 3-year cycle, there are a total of 42 distinct 3-year cycles that occur over the millennia. If the UK Reform Judaism movement chooses to publish a perpetual schedule (something akin to the A Complete Triennial System for Reading the Torah published by the Rabbinical Assembly), please let us know and we will take a look!
