Data provider | Read | Finbourne | Provided with LUSID |
The Lusid.Calendar.Date
provider enables you to write a Luminesce SQL query that retrieves information about dates in your calendars.
Note: The LUSID user running the query must have sufficient access control permissions to both use the provider and read calendar data stored in LUSID. This should automatically be the case if you are the domain owner.

Basic usage
select * from Lusid.Calendar.Date where <filter-expression>
Query parameters
Lusid.Calendar.Date
has parameters that enable you to filter or refine a query.
To list available parameters, their data types, default values, and an explanation for each, run the following query using a suitable tool:
select FieldName, DataType, ParamDefaultValue, Description from Sys.Field where TableName = 'Lusid.Calendar.Date' and FieldType = 'Parameter';
Data fields
By default, Lusid.Calendar.Date
returns a table of data populated with particular fields (columns). You can return a subset of these fields.
To list fields available to return, their data types, whether fields are considered 'main', and an explanation for each, run the following query using a suitable tool:
select FieldName, DataType, IsMain, IsPrimaryKey, SampleValues, Description from Sys.Field where TableName = 'Lusid.Calendar.Date' and FieldType = 'Column';
Note: Fields marked 'main' are returned by queries that start select ^ from Lusid.Calendar.Date
.
Examples

Example 1: Determine if a certain date is a holiday
select * from Lusid.Calendar.Date where LocalDate = '2023-12-25'
Example 2: Retrieve calendar dates for a certain year
select * from Lusid.Calendar.Date where CalendarCode = 'GBP' and LocalDate like '%2023%'
Example 3: Check for any bond payments due to mature on a holiday
You can join Lusid.Calendar.Date
with an instrument provider to check if a payment date falls on a holiday and subsequently how the payment date will be adjusted.
select
b.DisplayName,
b.MaturityDate,
b.LusidInstrumentId,
b.FlowConventionsRollConvention,
b.FlowConventionsSettleDays,
c.DateIdentifier
from Lusid.Instrument.Bond b
inner join Lusid.Calendar.Date c
on b.MaturityDate = c.FromUtc
where b.FlowConventionsPaymentCalendars like '%GBP%'
and c.CalendarCode like '%GBP%'
group by b.LusidInstrumentId;
The table of data returned by the query looks like this:
