38.1 - Dyddiau a nosweithiau - Days and nights

Notice the difference between the days and the nights! 'Dydd' is a masculine noun and 'Nos' is a feminine noun. Adjectives which follow feminine nouns undergo a Soft Mutation.

Dydd Sul - Sunday
Nos Sul - Sunday night
Dydd Llun - Monday
Nos Lun - Monday night
Dydd Mawrth - Tuesday
Nos Fawrth - Tuesday night
Dydd Mercher - Wednesday
Nos Fercher - Wednesday night
Dydd Iau - Thursday
Nos Iau - Thursday night
Dydd Gwener - Friday
Nos Wener - Friday night
Dydd Sadwrn - Sadwrn
Nos Sadwrn - Saturday night

To convey 'on' a certain day, all we need do is mutate 'dydd' to 'ddydd'.

dydd Mawrth - Tuesday
ddydd Mawrth - on Tuesday

Roedd 'Crimewatch' ar y teledu ddydd Llun.
- 'Crimewatch' was on the television on Monday.

Mae'r Grand National ar y teledu ddydd Sadwrn.
- The Grand National is on the television on Saturday.

As the consonant 'n' doesn't mutate, then 'nos Sadwrn' etc can convey 'Saturday night' or 'on Saturday night'. The context will make it clear.

Roedd 'Crimewatch' ar y teledu nos Lun.
- 'Crimewatch' was on the television on Monday night.

Mae 'Match of the Day' ar y teledu nos Sadwrn.
- 'Match of the Day' is on the television on Saturday night.

Nos Fercher mae'r gêm.
- The match is on Wednesday night.
