Editorial policy and corrections
DaysSinceCalc is written and maintained by Qudoos. Our goal is to provide reliable date arithmetic and clear, useful explanations. This policy describes the difference between calculated results and sourced editorial material, along with what we do when we find a mistake.
1. Calendar calculation methodology
The calculators use Gregorian calendar dates. The ordinary “days since” value is the number of calendar-date boundaries between the start and end dates. For example, January 1 to January 2 is one day, not two. Inclusive mode can include both endpoints. A week is seven days, while calendar months and years follow actual anniversary boundaries rather than a fixed 30- or 365-day approximation.
Leap years and timezones
February 29 is counted in leap years. A leap year is generally divisible by four, except century years that are not divisible by 400. Date-only results follow the visitor’s selected calendar dates; second-by-second displays follow the browser clock and may differ from calendar day totals around timezone or daylight-saving transitions.
2. Historical events and source standards
Historical timeline entries should identify a date, event, source organization and source URL. We favor original records, institutions, credible reporting and public historical archives. An event’s occurrence date must not be confused with a later article publication date or with a broad topic loosely associated with that period.
Where the date of an event is disputed or differs by timezone, we explain the convention rather than pretending a single date is unquestionable. If a relevant source is unavailable, the page may show a transparent empty state instead of fabricated filler.
3. Editorial approach to health and habit trackers
Streak counters provide arithmetic and organizational help. Any statement about physical or mental health should be attributed appropriately. We do not offer diagnosis or individualized treatment, and a numeric streak should never be presented as a substitute for professional advice.
4. Content authorship and editorial updates
Pages identify their responsible author/editor through a profile linked to Qudoos. Content may be revised to improve clarity, correct dates or replace outdated sources. Publication and modification dates follow WordPress records. They should only imply an update when meaningful content has actually changed.
5. How to report a correction
Email [email protected] with the affected URL, the date or phrase in question, the expected correction and a supporting reference if one is available. For a calculator bug, include the test dates and the counting mode. Reports are reviewed as editorial or technical corrections; sending one does not automatically guarantee a specific editorial change.
6. Conflicts of interest and advertising
If the site adds sponsorship or affiliate relationships, those should be identified where they affect content. The site does not currently claim a panel of independent reviewers or certified professional credentials. Reproduced material from external publishers is minimized and accompanied by source links rather than presented as our own reporting.
