Date / time format localization
We bring dates and times to the local format: day/month order, 12- or 24-hour format, the visitor's timezone. So that '03.04' is not read as April 3 by some and March 4 by others, and time is shown in the user's zone. To remove confusion that quietly harms trust and leads to errors in bookings/orders. Honestly upfront: this is a careful technical detail that reduces confusion, but its accuracy depends on correct locale data and timezone detection (not always perfect), and complex time scenarios (timezones, DST) require separate attention.
Date / time format localization — overview

Date/time format localization is bringing the display of dates and times to the user's expectations by their country/language: element order (DD.MM.YYYY vs MM/DD/YYYY), 12/24-hour format, month/day names in the right language, and showing time in the visitor's timezone where appropriate. Honestly about the value: it is a small but important detail — ambiguous dates (03.04) and time in a foreign zone lead to real errors in bookings, orders, schedules and undermine the feeling that 'the site is made for me'. Honestly about accuracy: the format depends on correct locale data, and showing 'local time' depends on detecting the user's timezone, which is not always accurate (VPN, device settings). So in critical places (bookings, events) it is more honest to show the zone explicitly ('15:00 Moscow time') rather than silently guess. Honestly about complex cases: operations with timezones and daylight saving time (DST) are a source of tricky bugs; for schedules/bookings this requires careful work, not just a format change. Honestly about the boundary: this is date/time format; number formats are a separate service (784). Honestly about the effect: less confusion and fewer errors, we do NOT guarantee sales growth by itself. Honestly about access: access to the templates/code is needed. Picture this: instead of 'the date reads ambiguously and time is in an unclear zone' — everything in the familiar local format and in the right zone. The base price starts from 7,000 ₽ (depends on the number of locales and the presence of time-dependent features).

FAQ
Will the site definitely show the user's local time?
In most cases yes, but honestly: showing 'local time' depends on detecting the user's timezone, which is not always accurate (VPN, device settings). So in critical places (bookings, events) we show the zone explicitly — '15:00 Moscow time' — instead of silently guessing, to avoid confusion.
It is just a format change, why are there nuances?
The date format itself — yes, simple. But time operations (timezones, daylight saving) are a known source of tricky bugs: a schedule can 'slip' by an hour. If you have bookings or events, this requires careful work, not just a display change — we account for this honestly.
How is this different from number localization?
These are different things. Here — dates and times (order, 12/24h, zone). Number localization (784) is digit and decimal separators (1 000,50 vs 1,000.50). Both are small, but both affect readability; we will honestly say whether you need both.
