How these tools are updated

• Calendar: re-check the current BS year at New Year (1 Baisakh) against a patro and the converter.
• Tax: replace slabs when a Finance Act or IRD notice lands; target Shrawan 1.
• GPA: replace the 2078 table only when MOEST or NEB publishes a new directive.

Each tool shows the last-verified date. A date is not a promise the law is unchanged today.
