Helpful things to include:

• For a calculation: the exact text you entered and the method (a shared link from the calculator is ideal).
• For a source: the reference (book, chapter or folio) and, if possible, a link to the text.
• For a date tool: the date, whether it was after sunset, and the result you expected.

We cannot give personal religious rulings. For questions about customs (for example which Adar to keep a yahrzeit in), please ask your rabbi.
