Date offset format for shortcut option
The from and to property in shortcuts options, which are used to calculate the start/end date of an shortcut option, share the same format which is number | Object and default to 0.
numbervalues are the offset in days calculated against “today”. eg.-1means{ startOf: 'day', days: -1 }, which is “yesterday”.Objectvalues have the type of{startOf: string=, days: number=, weeks: number=, months: number=, }.Name Type Default Description startOfstring='day'The base date. Supported values include 'day'/'week'/'month'/'quarter'/'year'.daynumber=- Offset in days. weeknumber=- Offset in weeks. monthnumber=- Offset in months. quarternumber=- Offset in quarters. yearnumber=- Offset in years.
The final date is calculated by accumulating the offset onto the base date.
The following example with labels may help to better understand the calculation logic. You can rapidly set shortcut options once you understand the underlying logic.
[
{
label: 'Last month',
// Turn back a month from the first day of current month,
// which is the first day of last month
from: {
startOf: 'month',
month: -1
},
// Turn back a day from the first day of current month,
// which is the last day of last month
to: {
startOf: 'month',
days: -1
}
},
{
label: 'This month',
