| In some date calculations, adding months or years can cause the date to fall |
| on a day of the month which is not valid (e.g. February 29th 2001 or |
| June 31st 2000). If overflow is allowed (as is the default), then the month |
| will be incremented accordingly (so, February 29th 2001 would become |
| March 1st 2001, and June 31st 2000 would become July 1st 2000). If overflow |
| is not allowed, then the day will be adjusted to the last valid day in that |
| month (so, February 29th 2001 would become February 28th 2001 and |
| June 31st 2000 would become June 30th 2000). |
| |
| AllowDayOverflow only applies to calculations involving months or years. |
| |
| If set to $(D AllowDayOverflow.no), then day overflow is not allowed. |
| |
| Otherwise, if set to $(D AllowDayOverflow.yes), then day overflow is |
| allowed. |

| Combines the $(REF Date,std,datetime,date) and |
| $(REF TimeOfDay,std,datetime,date) structs to give an object which holds |
| both the date and the time. It is optimized for calendar-based operations and |
| has no concept of time zone. For an object which is optimized for time |
| operations based on the system time, use $(REF SysTime,std,datetime,systime). |
| $(REF SysTime,std,datetime,systime) has a concept of time zone and has much |
| higher precision (hnsecs). $(D DateTime) is intended primarily for |
| calendar-based uses rather than precise time operations. |

| Returns the difference between the two $(LREF DateTime)s in months. |
| |
| To get the difference in years, subtract the year property |
| of two $(LREF DateTime)s. To get the difference in days or weeks, |
| subtract the $(LREF DateTime)s themselves and use the |
| $(REF Duration, core,time) that results. Because converting between |
| months and smaller units requires a specific date (which |
| $(REF Duration, core,time)s don't have), getting the difference in |
| months requires some math using both the year and month properties, so |
| this is a convenience function for getting the difference in months. |
| |
| Note that the number of days in the months or how far into the month |
| either date is is irrelevant. It is the difference in the month property |
| combined with the difference in years * 12. So, for instance, |
| December 31st and January 1st are one month apart just as December 1st |
| and January 31st are one month apart. |

| Converts this $(LREF DateTime) to a string. |
| |
| This function exists to make it easy to convert a $(LREF DateTime) to a |
| string for code that does not care what the exact format is - just that |
| it presents the information in a clear manner. It also makes it easy to |
| simply convert a $(LREF DateTime) to a string when using functions such |
| as `to!string`, `format`, or `writeln` which use toString to convert |
| user-defined types. So, it is unlikely that much code will call |
| toString directly. |
| |
| The format of the string is purposefully unspecified, and code that |
| cares about the format of the string should use `toISOString`, |
| `toISOExtString`, `toSimpleString`, or some other custom formatting |
| function that explicitly generates the format that the code needs. The |
| reason is that the code is then clear about what format it's using, |
| making it less error-prone to maintain the code and interact with other |
| software that consumes the generated strings. It's for this same reason |
| that $(LREF DateTime) has no `fromString` function, whereas it does have |
| `fromISOString`, `fromISOExtString`, and `fromSimpleString`. |
| |
| The format returned by toString may or may not change in the future. |

| Represents a date in the |
| $(HTTP en.wikipedia.org/wiki/Proleptic_Gregorian_calendar, Proleptic |
| Gregorian Calendar) ranging from 32,768 B.C. to 32,767 A.D. Positive years |
| are A.D. Non-positive years are B.C. |
| |
| Year, month, and day are kept separately internally so that $(D Date) is |
| optimized for calendar-based operations. |
| |
| $(D Date) uses the Proleptic Gregorian Calendar, so it assumes the Gregorian |
| leap year calculations for its entire length. As per |
| $(HTTP en.wikipedia.org/wiki/ISO_8601, ISO 8601), it treats 1 B.C. as |
| year 0, i.e. 1 B.C. is 0, 2 B.C. is -1, etc. Use $(LREF yearBC) to use B.C. |
| as a positive integer with 1 B.C. being the year prior to 1 A.D. |
| |
| Year 0 is a leap year. |

| Adds the given number of years or months to this $(LREF Date). A negative |

| the exact same $(LREF Date). However, the days can still be affected due |

| Returns the difference between the two $(LREF Date)s in months. |
| |
| To get the difference in years, subtract the year property |
| of two $(LREF Date)s. To get the difference in days or weeks, |
| subtract the $(LREF Date)s themselves and use the |
| $(REF Duration, core,time) that results. Because converting between |
| months and smaller units requires a specific date (which |
| $(REF Duration, core,time)s don't have), getting the difference in |
| months requires some math using both the year and month properties, so |
| this is a convenience function for getting the difference in months. |
| |
| Note that the number of days in the months or how far into the month |
| either $(LREF Date) is is irrelevant. It is the difference in the month |
| property combined with the difference in years * 12. So, for instance, |
| December 31st and January 1st are one month apart just as December 1st |
| and January 31st are one month apart. |

| Converts this $(LREF Date) to a string. |
| |
| This function exists to make it easy to convert a $(LREF Date) to a |
| string for code that does not care what the exact format is - just that |
| it presents the information in a clear manner. It also makes it easy to |
| simply convert a $(LREF Date) to a string when using functions such as |
| `to!string`, `format`, or `writeln` which use toString to convert |
| user-defined types. So, it is unlikely that much code will call |
| toString directly. |
| |
| The format of the string is purposefully unspecified, and code that |
| cares about the format of the string should use `toISOString`, |
| `toISOExtString`, `toSimpleString`, or some other custom formatting |
| function that explicitly generates the format that the code needs. The |
| reason is that the code is then clear about what format it's using, |
| making it less error-prone to maintain the code and interact with other |
| software that consumes the generated strings. It's for this same reason |
| $(LREF Date) has no `fromString` function, whereas it does have |
| `fromISOString`, `fromISOExtString`, and `fromSimpleString`. |
| |
| The format returned by toString may or may not change in the future. |

| it presents the information in a clear manner. It also makes it easy to |
| simply convert a $(LREF TimeOfDay) to a string when using functions such |
| as `to!string`, `format`, or `writeln` which use toString to convert |
| user-defined types. So, it is unlikely that much code will call |
| toString directly. |
| |
| The format of the string is purposefully unspecified, and code that |
| cares about the format of the string should use `toISOString`, |
| `toISOExtString`, or some other custom formatting function that |
| explicitly generates the format that the code needs. The reason is that |
| the code is then clear about what format it's using, making it less |
| error-prone to maintain the code and interact with other software that |
| consumes the generated strings. It's for this same reason that |
| $(LREF TimeOfDay) has no `fromString` function, whereas it does have |
| `fromISOString` and `fromISOExtString`. |
| |
| The format returned by toString may or may not change in the future. |
