Date Package Examples

This directory contains examples demonstrating how to use the date package, which provides utilities for working with dates and times in Go applications. The package offers a consistent way to parse, format, and manipulate dates using a standardized format.

Examples

1. Basic Usage Example

basic_usage_example.go

Demonstrates basic date parsing and formatting.

Key concepts:

• Parsing date strings into time.Time objects
• Extracting components from parsed dates (year, month, day, etc.)
• Formatting time.Time objects into standardized strings
• Parsing formatted dates back into time.Time objects

2. Optional Date Example

optional_date_example.go

Shows how to work with optional (nullable) dates.

Key concepts:

• Parsing nil and non-nil date strings
• Handling nil date pointers
• Formatting nil and non-nil dates
• Using optional dates in structs

3. Error Handling Example

error_handling_example.go

Demonstrates error handling for invalid dates.

Key concepts:

• Handling invalid date formats
• Detecting validation errors
• Graceful error handling in functions
• Processing multiple date parsing attempts

4. Time Zone Example

time_zone_example.go

Shows how to work with dates in different time zones.

Key concepts:

• Parsing dates with different time zones
• Comparing dates from different time zones
• Converting between time zones
• Formatting dates with time zone information
• Working with local time zone

Running the Examples

To run any of the examples, use the go run command:

go run examples/date/basic_usage_example.go

Key Features of the Date Package

1. Standardized Date Format: Uses RFC3339 format consistently throughout the application.

2. Date Parsing: Parse date strings into time.Time objects with proper error handling.

3. Date Formatting: Format time.Time objects into standardized strings.

4. Optional Date Handling: Special handling for nil date pointers, allowing for nullable dates in your application.

5. Error Handling: Proper validation and error handling for invalid date formats.

Best Practices

1. Consistent Date Format: Always use the package's standard date format for consistency across your application.

2. Error Handling: Always check for errors when parsing dates.

3. Nil Handling: Use the optional date functions when dealing with dates that might be nil.

4. Time Zones: Be aware of time zone implications when parsing and formatting dates.

5. Date Comparisons: When comparing dates, ensure they are in the same time zone to avoid unexpected results.
