Guide hub

Guides answer narrow recurring questions

Guide pages are built for readers who search a specific question, such as whether USPS is open on a holiday, when a federal tax deadline falls, or how school FAFSA deadlines differ from the federal deadline. Each guide should provide a direct answer first, then explain source boundaries and verification steps.

The most useful guide is not the longest page. It is the page that separates what the official source actually supports from what still needs a local, school, state, bank, IRS, USPS, or Federal Student Aid check.

How to choose the right guide

Tax guides

Use these for IRS filing dates, estimated tax schedule context, and filing-preparation organization. Do not use them to calculate tax, decide whether a payment is owed, or replace IRS instructions.

Holiday and service guides

Use these for OPM, USPS, and Federal Reserve holiday schedule context. If you need a specific branch, post office, collection box, agency lobby, or private-bank status, verify that source directly.

Student aid guides

Use these for Federal Student Aid deadline layers, account preparation, contributor readiness, and correction paths. Do not use them to estimate awards, eligibility, or school-specific aid timing.

Reader workflow

  • Start with the direct answer. Confirm that the page matches the exact year, cycle, and jurisdiction you need.
  • Read the boundary section. Most pages intentionally stop before advice, calculations, or local operating guarantees.
  • Open the official source. Use the linked source if the task is time-sensitive or if the last verified date is no longer recent.
  • Use the correction path. Report official-source changes so the site can update the affected guide.

Guide quality standard

Every guide should make the next verification step obvious

A guide page should answer a narrow public-information question and then point to the official path that controls the answer. For this site, that usually means IRS for federal tax dates, Federal Student Aid for FAFSA deadlines, OPM for the federal employee holiday calendar, USPS for Postal Service holiday and location checks, or Federal Reserve K.8 for Federal Reserve holiday schedules.

The guide index helps readers choose among those pages. It should also make clear why some questions cannot be answered by a single national calendar. A private bank branch, school financial aid office, state tax agency, post office lobby, or federal agency location can publish its own notice that a national source page does not cover.

How the guides are maintained

Date-sensitive guides are written with reusable boundaries: last verified date, official source links, jurisdiction, year or cycle, and a correction path. When a source changes, the relevant guide should be checked against the matching calendar and topic hub so readers do not see conflicting summaries across the site.
