Chile will not change clocks in April 2015 or thereafter; its new standard time will be its old daylight saving time. We have updated Hebcal’s candle-lighting times engine to reflect the change.

If you downloaded or printed candle-lighting times for Santiago or any other city in Chile, be sure to re-download sometime before Pesach.

In general, Jewish Holidays begin the evening before the date specified. This is because the Jewish day actually begins at sundown on the previous night. Sometimes, for clarity, the Erev holiday is also included to indicate that the holiday begins the evening before.

For example, in the April 2015 calendar below, Erev Pesach is listed as April 3rd and the first day of Pesach is listed as April 4th. This means that the holiday of Pesach begins on the evening on April 3rd.

And, Rosh Chodesh Iyyar is listed on April 19. This means that Rosh Chodesh begins on the evening of April 18, even though the Erev is not explicitly mentioned on the calendar.

  5. Visit the Hebcal Custom Calendar latitude/longitude page at;geo=pos
