About WCalendar.com
WCalendar.com helps people turn work rules into calendar-ready output: shift schedules, business days, pay periods, ICS files, CSV exports, and add-to-calendar links.
Our Mission & Why We Built WCalendar
WCalendar was built to solve a practical scheduling problem: shift workers, nurses, firefighters, and payroll planners often need to turn a repeating work rule or pay-period cycle into an importable calendar file without wrestling with complex spreadsheets.
Many workforce portals lock schedules behind proprietary logins or lack clean exports. WCalendar transforms deterministic shift patterns, federal holiday rules, and pay period cycles into standard calendar files (.ics) and spreadsheets (.csv) directly in your browser—with no accounts, no paywalls, and no server-side storage of your schedule.
Shift calendar generators for repeating work/off patterns
Business-day calculators for weekdays and US federal holidays
Biweekly pay period calendars for planning pay dates
ICS files, CSV exports, and add-to-calendar links
Engineering Rigor & Verification Standards
Accuracy in work scheduling and payroll planning is paramount. We treat calendar generation not as simple static text, but as a deterministic engineering problem backed by rigorous automated testing.
RFC 5545 Compliant
All generated .ICS calendar feeds strictly adhere to the Internet Calendaring and Scheduling Core Object Specification (RFC 5545), ensuring seamless cross-compatibility across Google Calendar, Apple Calendar, and Microsoft Outlook.
OPM Federal Holiday Rules
Our business day calculations accurately model statutory and observed US federal holidays in accordance with Title 5 Section 6103 of the United States Code and US Office of Personnel Management (OPM) guidelines, including Friday/Monday observation adjustments.
100% Client-Side Privacy
Your shift labels, schedule cycles, and working hours are computed in your web browser memory. No employee shift records or personal identifiers are ever transmitted to or stored on our servers.
How We Verify Calculations & Reference Guides
Every calculator and reference guide on WCalendar is built on deterministic calendar mathematics and verified against primary public-domain standards. Our date, week-number, shift-cycle, and holiday engines are validated by automated unit tests across common years, leap years, and year-end boundaries.
Where our guides discuss workplace rules—such as federal holiday observance under 5 U.S.C. § 6103, workweek and public-safety overtime frameworks under the Fair Labor Standards Act (29 U.S.C. § 207 and 29 CFR Parts 553 & 778), Federal Reserve Financial Services ACH holiday schedules, ISO 8601 week numbering, and IETF RFC 5545 iCalendar formatting—we link directly to the underlying statutory or technical specification so you can verify the primary source yourself.
Important Operational Boundaries
- WCalendar is not a replacement for Google Calendar, Outlook, or Apple Calendar.
