Understanding annual planning
Sri Lanka calendar 2026: planning guide
The Sri Lanka calendar for 2026 combines all twelve months with ISO week numbers and the public-holiday coverage available for this country. Nationwide dates and regional dates are kept distinct, because a regional holiday may not create a day off at every workplace in Sri Lanka.
No published school-holiday dataset is stored for this country and year. This should not be interpreted as an absence of school breaks; official education authorities remain the source for unpublished schedules.
The linked solar calendar provides daily sunrise and sunset values for its named reference location, including its time zone and daylight-saving changes. Values for another location in the country can differ noticeably.
Separate annual pages list every ISO-week range and all primary Moon phases. This country page stays focused on the twelve-month grid and public-holiday scope while preserving direct access to the more detailed datasets.
FAQ
Frequently asked questions about the Sri Lanka calendar 2026
Are regional holidays valid throughout Sri Lanka?
No. A regional date applies only in the scope printed next to it. Select or verify the relevant subdivision before relying on it.
Why can week 1 begin in the previous year?
ISO week 1 is the week with the first Thursday. Its Monday can therefore fall in late December.
Can the public holidays be imported into another calendar?
Yes, when holiday coverage exists, the ICS download adds the listed dates to compatible calendar applications.
Are school-holiday dates legally binding?
They reproduce published data, but the responsible education authority and school remain decisive for attendance planning.
Which place are the solar times for?
The linked solar calendar names its reference place, coordinates and time zone.
