Date Ranges

LightLead supports two ways to define a report period: preset ranges and custom dates.

Preset ranges

These are dynamic periods that are automatically recalculated relative to the current date.

Preset	Description	Boundaries
`today`	Today	00:00 – the current moment
`yesterday`	Yesterday	00:00 – 23:59 of the previous day
`last_3_days`	Last 3 days	3 days ago 00:00 – today
`last_7_days`	Last 7 days	7 days ago 00:00 – today
`last_14_days`	Last 14 days	14 days ago 00:00 – today
`last_30_days`	Last 30 days	30 days ago 00:00 – today
`last_90_days`	Last 90 days	90 days ago 00:00 – today
`this_week`	This week	Mon 00:00 – the current moment
`last_week`	Last week	Mon 00:00 – Sun 23:59
`this_month`	This month	The 1st 00:00 – the current moment
`last_month`	Last month	The 1st 00:00 – the last day 23:59
`this_quarter`	This quarter	Start of quarter – the current moment
`last_quarter`	Last quarter	Start of quarter – end of quarter 23:59
`this_year`	This year	January 1 00:00 – the current moment
`last_year`	Last year	January 1 00:00 – December 31 23:59
`all_time`	All time	From the earliest available date – today

Defined explicitly with start and end dates:

json

{
  "start": "2026-01-01",
  "end": "2026-01-31"
}

Date format: YYYY-MM-DD (ISO 8601)
start is included in the range (00:00:00)
end is included in the range (23:59:59)
start can't be later than end
The maximum range length depends on the plan (see Limits)
The earliest available date depends on the source — not all sources store data for every period

When using comparison with the previous period, the system automatically picks an equivalent-length period:

It's important to distinguish between:

Event date — when the click/impression/conversion happened (from the source's API)
Load date — when the data landed in LightLead

By default, all reports are built by event date.

Day boundaries are determined by the time zone of the source account. More details in Time Zones.
