KingCalendar is a fully-featured VCL calendar component library for Delphi 10.2 through 13, supporting Win32, Win64, and Win64x platforms. Open source under the MIT License.
Full Month Grid
Renders a complete month view with day selection, blocked days, flagged days, and per-cell color customization.
9 Built-in Color Sets
Choose from nine named color schemes via ColorSet1–ColorSet9 properties, or build your own.
Companion Controls
Month/year/day spin and combo controls, week labels, a navigator panel, and a month-bar all bind directly to the calendar.
Popup & Dialog Modes
TKingPopup drops down like a date-picker; TKingDateDialog is a standalone date selection dialog.
Database Aware
Six DB-aware components (TDBKingCalendar, TDBKingDateSpin, TDBKingTimeSpin, TDBKingMDYSpin, TDBKingHMSpin, TDBKingDateDialog) bind to TDataSource for seamless dataset integration.
LiveBindings Support
All date/time controls register observable members for Delphi's visual data binding designer. Works with TBindSourceDB and TBindSourceAdapter.
High DPI & VCL Styles
Fully compatible with Delphi's High DPI scaling and VCL Styles runtime theming.
No External Dependencies
Pure Object Pascal. Ships pre-compiled for every supported Delphi version — no third-party runtime required.

Inline date, time, and MDY spin-button editors for quick keyboard-friendly date entry in any form.
