# Namespace Temporalio.Api.Schedule.V1

### Classes

- CalendarSpec
CalendarSpec describes an event specification relative to the calendar, similar to a traditional cron specification, but with labeled fields. Each field can be one of:

*: matches always x: matches when the field equals x x/y : matches when the field equals x+n*y where n is an integer x-z: matches when the field is between x and z inclusive w,x,y,...: matches when the field is one of the listed values Each x, y, z, ... is either a decimal integer, or a month or day of week name or abbreviation (in the appropriate fields). A timestamp matches if all fields match. Note that fields have different default values, for convenience. Note that the special case that some cron implementations have for treating day_of_month and day_of_week as "or" instead of "and" when both are set is not implemented. day_of_week can accept 0 or 7 as Sunday CalendarSpec gets compiled into StructuredCalendarSpec, which is what will be returned if you describe the schedule.

- IntervalSpec
IntervalSpec matches times that can be expressed as: epoch + n * interval + phase where n is an integer. phase defaults to zero if missing. interval is required. Both interval and phase must be non-negative and are truncated to the nearest second before any calculations. For example, an interval of 1 hour with phase of zero would match every hour, on the hour. The same interval but a phase of 19 minutes would match every xx:19:00. An interval of 28 days with phase zero would match 2022-02-17T00:00:00Z (among other times). The same interval with a phase of 3 days, 5 hours, and 23 minutes would match 2022-02-20T05:23:00Z instead.

- MessageReflection
Holder for reflection information generated from temporal/api/schedule/v1/message.proto

- Range
Range represents a set of integer values, used to match fields of a calendar time in StructuredCalendarSpec. If end < start, then end is interpreted as equal to start. This means you can use a Range with start set to a value, and end and step unset (defaulting to 0) to represent a single value.

- ScheduleListEntry
ScheduleListEntry is returned by ListSchedules.

- ScheduleListInfo
ScheduleListInfo is an abbreviated set of values from Schedule and ScheduleInfo that's returned in ListSchedules.

- ScheduleSpec
ScheduleSpec is a complete description of a set of absolute timestamps (possibly infinite) that an action should occur at. The meaning of a ScheduleSpec depends only on its contents and never changes, except that the definition of a time zone can change over time (most commonly, when daylight saving time policy changes for an area). To create a totally self-contained ScheduleSpec, use UTC or include timezone_data.

For input, you can provide zero or more of: structured_calendar, calendar, cron_string, interval, and exclude_structured_calendar, and all of them will be used (the schedule will take action at the union of all of their times, minus the ones that match exclude_structured_calendar).

On input, calendar and cron_string fields will be compiled into structured_calendar (and maybe interval and timezone_name), so if you Describe a schedule, you'll see only structured_calendar, interval, etc.

- StructuredCalendarSpec
StructuredCalendarSpec describes an event specification relative to the calendar, in a form that's easy to work with programmatically. Each field can be one or more ranges. A timestamp matches if at least one range of each field matches the corresponding fields of the timestamp, except for year: if year is missing, that means all years match. For all fields besides year, at least one Range must be present to match anything. TODO: add relative-to-end-of-month TODO: add nth day-of-week in month
