Meta Pages Date and Time
Meta Pages data is tied to the Page's time zone. Understanding the specifics of working with dates is important for correctly interpreting metrics.
Time Zone
Facebook Page data uses Pacific Time (UTC-8/UTC-7) by default. This differs from the Meta Ads ad account's time zone.
Consequence: when comparing Meta Pages and Meta Ads data for the same day, discrepancies may occur due to the time zone difference.
Date Formats
All dates in the API use the YYYY-MM-DD format:
2026-07-25Aggregation Periods
Daily Aggregation (day)
{ "period": "day" }Data for each day separately. Available for the last 90 days.
Weekly Aggregation (week)
{ "period": "week" }Data grouped by weeks (Monday-Sunday). Available for 2 years.
28-Day Aggregation (days_28)
{ "period": "days_28" }A rolling 28-day period. Available for 2 years.
All Time (lifetime)
{ "period": "lifetime" }Aggregated data for the entire lifetime of the Page.
Time Range (since/until)
The Pages Insights API supports since and until parameters for specifying an arbitrary range:
since=2026-07-01
until=2026-07-25Unix timestamp is also supported, but not recommended — use YYYY-MM-DD.
Data Delay
Meta Pages data updates with a significant delay:
| Period | Availability | Delay |
|---|---|---|
| Today | Unavailable | N/A |
| Yesterday | Limited | 24 hours |
| 2-3 days ago | Partial | 48 hours |
| 4+ days ago | Full | — |
Important: unlike Meta Ads, Meta Pages data is not available in real time. The minimum delay is 24 hours.
Recommendations
- Don't analyze data younger than 2 days — it's incomplete
- Use 28-day periods for stable trends
- Compare periods of equal length — week-over-week, 28d-over-28d
- Account for the time zone difference with Meta Ads when doing cross-connector analysis
