Notes

Since the Jewish day begins at sunset, you should enter the following day if the yahrtzeit/anniversary occurred after sunset. Likewise, yahrtzeit candles should be lit at sunset on the day prior to the one shown on the display pages. Similar considerations apply to the calendar and holiday pages.

As usual, there are many different traditions about handling unusual dates when commemorating anniversaries according to the Jewish calendar. I have tried to accomodate all the traditions of which I am aware on the form above; you should determine which tradition is appropriate for you and select accordingly.

Ticking the "Yahrtzeit" radio box will use the following conventions:

  1. If the original date is the 30th of Kislev or Heshvan, and the anniversary year has only 29 days in that month:
    • If there are only 29 days in the month for the first anniversary year, the anniversary is observed on the 29th.
    • Otherwise, the anniversary is observed on the first day of the following month.
  2. When the original date falls in Adar of a non-leap-year, the yahrtzeit is observed in Adar-I of a leap year.
  3. When the original date was the 30th of Adar-I in a leap year, the yahrtzeit is observed on Adar 29 of a non-leap-year.
  4. Other dates in Adar-I and Adar-II are observed on the corresponding date in Adar for a non-leap-year.

The "Other Anniversary" calculations are less complicated than "Yahrtzeit". Although it is intended for events like birthdays and wedding anniversaries, these calculations are also used by many for Yahrtzeits as well. Ticking the "Other Anniversary" radio box will use the following conventions.

  1. If the original date is the 30th of Kislev or Heshvan and the anniversary year has only 29 days in that month, the anniversary is observed on the first day of the following month.
  2. When the original date falls in Adar of a non-leap-year, the anniversary is observed in Adar-II of a leap year.
  3. When the original date was the 30th of Adar-I in a leap year, the anniversary is observed on Nisan 1 of a non-leap-year.
  4. Other dates in Adar-I and Adar-II are observed on the corresponding date in Adar for a non-leap-year.

Some have the tradition that the anniversary of an original date of Adar in a non-leap-year should be observed in both Adar-I and Adar-II in a leap year. If that is your tradition, you should check the Double-Adar checkbox.

Some have the tradition that, when the original date was the 30th of Adar-I in a leap year, since that day is observed as Rosh Hodesh Adar-II, the anniversay should be observed on Shvat 30, which is observed as Rosh Hodesh Adar, in a non-leap-year. If that is your tradition, you should check the Shvat30 checkbox.

Ticking the "Gregorian" box will show the Gregorian date in successive Hebrew years. This has no halakhic significance, but can show items of interest, e.g. when does my civil birthday fall during Chanukah?

The display pages show 50 anniversary dates at a time, which is suitable for printing as a single page on most printers. You may display further dates by hitting the Continue button on the display pages, optionally entering the Hebrew year with which you wish to start.
