Does Posting Time Actually Affect Reach?
Yes — but less than most people think, and the effect varies by platform and audience. Professional networks tend to be checked during the working week, while entertainment-led platforms often see activity around commutes, breaks and evenings. Algorithmic feeds can continue distributing a post long after publication, whereas faster chronological feeds make the initial posting window more important.
The most reliable approach is to let your own data guide you rather than treating generic windows as guarantees. A B2B SaaS audience checks social platforms differently from a fitness creator's followers. Most platforms provide native analytics showing when your specific followers are active; that first-party data should replace general benchmarks once you have enough of it.
Shared Platform Timing Dataset
General starting-point windows consolidated from the existing Key For Riches tool and guide. They are directional benchmarks, not platform guarantees; replace them with first-party audience analytics when available. The times below are expressed in the audience's local timezone; the finder converts them for a chosen calendar week using IANA timezone and daylight-saving rules.

Why Real Timezones and Dates Matter
A fixed UTC offset is not a timezone. India uses a half-hour offset, several regions use quarter-hour offsets, and countries that observe daylight saving can change their relationship to another location during the year. The finder therefore uses city-based IANA identifiers such as Asia/Kolkata and America/New_York, plus the actual planning week, instead of asking you to guess a fixed UTC number.
If your audience spans several regions, run the finder for each primary audience timezone and stagger posts where practical. A scheduling tool can then hold those city-based times without forcing you to recalculate offsets manually.
Consistency Beats Timing Optimisation
The most important timing factor is not a single perfect hour; it is whether you publish consistently enough to learn from real performance. Use the shared dataset as a starting schedule, then compare reach and engagement by day and time. Replace the generic slots with the patterns your own audience demonstrates.
