Sat, 26 March 2022 after sunset is in fact the next Hebrew day, e.g. no longer Shabbat, so in fact it is correctly Parashat Tazria. 

Sat, 26 March 2022 before sunset is Shabbat, Parashat Shmini.

Please examine the "after sunset" box when using the date converter and remember to check the box only when you wish to convert a date after sunset.

Hi, thanks for using Hebcal.

Our website agrees with you and we publish Tzav for this coming Shabbat. Where did you see a page that said 19 March 2022 is Parshat Shemini?

Hi, thanks for the excellent explanation. We're so very sorry for any confusion or difficulty you experienced here.

In November 2020, the Committee on Jewish Law and Standards of the Rabbinical Assembly voted to change how triennial Torah readings work in year 3 for some of the Torah portions.

The CJLS modified the triennial cycle for some combined parshiyot to change the reading for year 3 to be the third section of the parashah.

The following parshiyot have been modified:

• Vayakhel
• Tazria
• Achrei Mot
• Behar
• Chukat
• Matot

Further details are available in the responsa: Modification of the Triennial Cycle Readings for Combined Parashot in Certain Years, Rabbi Miles B. Cohen, November 16, 2020

We were unaware of the CJLS responsa for about a year -- and then, in December 2021 we updated our Torah reading pages to match the new schedule.

It's obviously up to the rabbi of your congregation to decide, but in my (also layperson's) opinion, it seems perfectly acceptable for a congregation to continue to use the original triennial Torah readings that the CJLS first published in 1998 and Hebcal.com republished until December 2021.

Parashat Tazria in 2022 happens to be a 3-sefer-Torah Shabbat! Shabbat HaChodesh coincides with Rosh Chodesh Nisan once every 3-4 years. We wrote a short article about this on our website:

You can tell this by examining the Parashat Tazria page and looking at the special aliyot listed in green.

If your mother passed away on March 18, 2004 then indeed the yahrzeit is observed in Adar I in leap years and Adar during ordinary years.

In fact, this is exactly what the Hebcal Yahrzeit + Anniversary calendar produces:

Where are you seeing different results for March 18, 2004?

Hi, thanks for using Hebcal.

We regret that we do not currently offer a personalized zmanim service (alot haShachar, mincha ketana, etc).

We do offer candle-lighting and havadalah times for holidays and fast/start end times via https://www.hebcal.com/hebcal

Hi, thanks for using Hebcal's triennial Torah Reading feature.

In December 2021 we updated our Triennial readings to reflect the November 2020 responsa from the CJLS which modified the 3rd year readings for a half-dozen parshiyot. We published a short note about this change on the Hebcal.com website here:

https://www.hebcal.com/home/3824/triennial-torah-reading-revision

Since you reference Yad LaTorah from 2002, this obviously was published before the November 2020 CJLS responsa. So Yad LaTorah was correct at the time it was published, but it has become out-of-date.
