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 founded by software engineers and operations researchers who noticed a persistent problem: modern shift workers, healthcare professionals, first responders, and payroll administrators frequently struggle to import complex shift patterns into everyday calendar apps.
Most enterprise workforce management systems lock schedules behind proprietary portals, complex mobile apps, or paywalls. We believe basic work schedules and date math should be open, private, and effortless. WCalendar bridges this gap by transforming complex shift rules and pay periods into standard, importable calendar feeds (.ics) and spreadsheets (.csv) in seconds—with no accounts, no credit cards, and no tracking.
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.
Editorial Principles & Content Standards
Every article, schedule breakdown, and payroll reference guide published on WCalendar is authored or reviewed by specialists in operations planning, labor mathematics, and schedule compliance. We do not publish automated, thin, or AI-hallucinated schedules.
Our guides incorporate statutory federal labor guidelines (including FLSA 7(k) public safety exemptions, statutory 40-hour workweeks, and 9/80 workday split rules) to give shift workers and employers accurate, real-world context for how repeating patterns function in practice.
Important Operational Boundaries
- WCalendar is not a replacement for Google Calendar, Outlook, or Apple Calendar.
- WCalendar does not provide payroll, legal, employer-policy, or union-agreement advice.
- WCalendar does not save user-created schedules or publish them for other users.
Always verify generated dates with your employer, collective bargaining agreement, or payroll provider before making binding operational decisions.
