No. The math runs in your existing date widget, which handles leap years, DST transitions, business-day skipping, and holiday-calendar lookups through whatever date library it uses. SleekRank reads the variant row from your sheet and renders the surrounding copy, the operation label, the unit, and the variant-specific FAQs. The widget reads the operation, unit, and reference_mode columns as parameters.

Through a holiday-calendar config on the base page. The widget loads the calendar for the selected region from a config block on the base WP page, then skips weekends and listed holidays when computing business-day operations. The variant row's reference_mode column tells the widget to enable business-day mode for /date/business-days-from-today/ and to ignore the calendar for /date/days-between-two-dates/.

Yes, in two ways. Either ship one calendar per region as part of the base page config and let users pick from a dropdown on the widget, or split into per-region page groups with separate base pages like /date/us/business-days-from-today/ and /date/uk/business-days-from-today/. The second approach scales better when regional copy differs substantively. The first approach is simpler for sites with a primary region.

Document the convention explicitly per variant. Days-between calculations conventionally exclude the start date and include the end date, but legal and contract contexts sometimes count both, and rental and hotel contexts sometimes count neither. The FAQ column for each variant should call out the convention the widget uses and link to the alternative when context matters. /date/days-between-two-dates/ ships an exclusive-start, inclusive-end default.

Most date-difference calculators work in calendar days and ignore DST entirely because the day count is unaffected. If a variant operates in hours or minutes, the widget should use a date library that handles DST correctly, like Luxon or date-fns with timezone support. Surface the gotcha in the FAQ column for hour-level variants: the period across a spring-forward weekend is 23 hours, not 24.

Yes, if your widget supports a live countdown mode. Add a countdown_target column to the relevant rows and inject it onto the widget data attribute via selector mapping. /date/weeks-until-target/ then renders a live updating counter alongside the static result. The static result handles SEO indexing because crawlers see the computed copy; the live counter improves the on-page experience.

Lean on operation-specific FAQs and worked examples. /date/days-between-two-dates/ and /date/months-between-two-dates/ share structure but the worked examples and FAQs should differ substantially. Days-between examples lean on contract math; months-between examples lean on tenure or age math. Two near-identical variants like days-between and date-difference should collapse to one slug rather than competing in the index.

Yes. Drop the HowTo JSON-LD on the base page once and inject operation-specific step copy through selector or meta mappings tied to the row. The visible steps and the schema pull from the same column so they stay in sync. Validate the result with the Rich Results Test after the first batch publishes to catch any mapping mismatches before they propagate across the thirty-variant set.
