About CompliCalendar
Compliance is complicated. We keep it honest.
CompliCalendar is a free, public reference for the dates that run the workplace year — 17 OSHA and HR compliance deadlines plus dozens of awareness months, industry observances, and fun team days. Our goal is simple: be the most trustworthy, easiest-to-use calendar of workplace dates on the internet.
Sourced from primary agencies
Every deadline links back to the official agency — OSHA, DOL, IRS, EEOC, CMS — not secondhand summaries.
Verified, not guessed
Dates are checked against the issuing authority. Where a deadline shifts year to year, we say so instead of inventing a date.
Updated every year
We refresh dates as agencies publish them and review the full calendar ahead of each new year.
How we build the calendar
- 1Identify the datefrom the issuing authority's official guidance or regulation.
- 2Summarize who it affects, what's required, and what happens if it's missed — in plain language, with the official source linked.
- 3Review annually and update as agencies announce new dates, forms, or thresholds.
Primary sources we rely on
