Everything a finance team needs

From custom fiscal year starts to public-holiday handling, role-based access and audit-ready logs — packed into one self-hostable app.

Custom fiscal years

Any FY start month/day, week-start day and start-year vs end-year FY labelling per entity. UK April 6th, US October 1st, Japan April 1st, you name it.

Public holidays, automated

Pre-loaded for 108 countries via the Nager.Date API, with manual overrides for company-specific days off.

REST API + OpenAPI

A clean versioned API with bearer-token auth, per-key rate limits and a published OpenAPI 3.0 spec. Wire it into any system.

Webhooks & events

HMAC-signed event delivery on entity created, calendar generated, holiday added, and more. Each delivery is logged for replay and debugging.

Enterprise-grade auth

Granular roles (admin / manager / editor / viewer), TOTP two-factor, login throttling, password policy and append-only audit log.

Export anywhere

CSV, Excel and iCal feeds straight from the UI. Subscribe Outlook or Google Calendar to your fiscal period boundaries.

Multi-database

Runs unchanged on SQLite, PostgreSQL, MySQL/MariaDB and Microsoft SQL Server. Same pure-Python calendar engine on every backend.

BI-ready schema

Direct SQL access to a normalised fiscal calendar table. Plug Power BI, Tableau, Looker, or Metabase straight in.

White-label ready

Customise product name, logo, primary colour and support email — every page reflects your brand without code changes.
