• Immutable Date Libraries - Ensures predictable state changes by returning new date objects after every operation to prevent side effects.
• Date Arithmetic Logic - Provides a set of functions for calculating differences and adjusting time values with configurable overflow behavior.
• Date String Parsers - Creates date objects from ISO 8601 strings while applying specific IANA timezone offsets.
• Date Validation Utilities - Converts date strings and ISO 8601 formats into date objects while verifying their structural correctness.
• Date Formatting Utilities - Converts date objects into human-readable strings using localized styles or custom formatting tokens.
• Date String Formatters - Transforms date objects into strings using locale-aware patterns and timezone offsets.
• Localized Formatters - Transforms dates into human-readable strings based on specific language and regional settings using the Intl API.
• Date Difference Calculators - Finds the duration between two dates as a structured object or a specific unit of time.
• ISO 8601 Standards - Provides a compatibility layer to validate and transform date strings according to the ISO 8601 international standard.
• ISO 8601 Parsers - Provides a dedicated utility for validating and converting ISO 8601 strings into date objects with timezone handling.
• Timezone Management - Implements logic to map IANA timezone identifiers to numeric offsets for geographic date normalization.
• Internationalization API Integrations - Utilizes the browser native Internationalization API for region-specific date formatting and locale-aware name generation.
• Internationalized Date Formatting - Transforms date objects into human-readable strings using locale-aware patterns and language settings.
• Date Component Extractors - Retrieves granular parts of a date value, such as the day of the year or locale-specific month names.
• Component Mutators - Allows updating specific parts of a date, such as the hour, minute, or day, to a precise value.
• Temporal Boundary Normalization - Provides capabilities to set a date to the start or end of a specific period like a day, month, or year.
• Token-Based Parsers - Matches custom date format strings against regex patterns to extract and transform date components.
• Date Comparison Utilities - Checks if one date is before, after, or equal to another, or if they share specific time components.
• Temporal Boundary Normalization - Provides utilities to snap date objects to the start or end of days, hours, minutes, months, weeks, or years.
• Date Utilities - Tree-shakable library for native Date objects.
