If you read in the app a wrong value for Sunset or Sunrise, compared to your local congregation or some other source, it might indicate that your app is configured to take Elevation (Altitude) into account whereas your comparison source does not.
A few hundred meters Elevation might account for a difference of one to several minutes in the time of perceived sunset by the observer (when standing on a hilltop, one can see the Sun a bit longer above the horizon line, than one standing at sea level), for simple geometrical reasons. However, unless for mountain locations at high altitude, this parameter is generally ignored in most congregations.
While the GPS detection provides an accurate elevation measurement, you might want to set it to zero anyway. You can do this in the Geo Location Details screen in your app:
Click Edit on your current location:
Then, erase the Elevation field:
I added a yahrzeit anniversary for my sister who died on August 29, 2026. The app reports a 2027 date of Aug 29,2027, which translates to 16 Av, even though the Hebrew date says 16 Ellul. Not sure if relevant, but I have a different yahrzeit on Ellul 16. Please advise.
Thanks,

Dear Robin,
I am very sorry to hear. May her memory be a blessing.
This occurrence on Aug. 29 2027, is the 12 Months — not the subsequent recurring yahrzeit.
The first year after a person died, we observe a Zicaron after 12 months, even if the actual year has an Adar Bet — which is the case for 5787.
I hope this answers your question,
Best,
Shana tova,
Gabriel
Hi Gabriel,
