Persian Date Picker Svelte

Persian Date Picker Svelte is a package which supports both Jalali and Gregorian calendars, inspired by Date Picker Svelte

Features:

• Theming
• Custom formats
• Internationalization for the Gregorian Calendar (i18n)
• Auto-punctuation (e.g typing "20201111111111" gives you "2020-11-11 11:11:11" with the default format)
• Keyboard shortcuts
